I disagree with part of the previous answer and my math skills aren’t great and my work is chicken scratch until I figure it out…

Sophie and Shelly is easy because Sophie only has to have more coins in half dollars than Shelly has in pennies. Shelly has a set amount of 16.71 less than Sophie.

Sophie has 34 half dollars and Shelly has 29 pennies
17.00 = (34 coins)
0.29 = (29 pennies)
17.00 – .29 = 16.71
agree with previous answer

Tyler has nickles and must have 10 more coins than Hal
Hal has dimes
Perlin has quarters and must have 15 more coins than Hal
Combined they have $7.85 in coins

Tyler has 19 nickles for a total of $0.95
Hal has 9 dimes for a total of $0.90
Perlin has 24 quarters for a total of $6.00

Ruh roh! I didn’t check Daria’s answers thoroughly. In fact, you, Theadoptedones, came up with the same answers that I did, the same ones that meet the criteria.

Why? Why would you do this? Math is not my friend. Not then, not now. I can’t believe I tried. However, I do not have that much spare time and I already know that I will have nightmares over math. I’m going to go over to the corner and cry now.

Took me 2 minutes and I came up with the same answers as Theadoptedones. Of course, I failed algebra both in high school and college so I used a spreadsheet. Theory is the same, but other than showing my code I can’t tell you how I figured it out.

I’m not even going to try it, because I know I’m not smarter than a 3rd grader. I gave up helping my daughter with her homework when she was in 3rd grade last year. Math is a whole other animal and taught completely different than when we were kids.

Holy Toledo! 3rd grade? Answer (bc I want starbucks ðŸ™‚

Shelley – 29

Sophie – 34

Tyler – 90

Hal – 9

Perlin – 135

P+H+T=7.85

(H+15).25+.1H+(10+h).05=7.85

.25H=$3.75+.1H+.5+.05H=$7.85

.4H=3.6

H=9

Sophie=(Sh+5).50

.01(shelley) = Sophie – 16.71

.01Sh=(Sh+5).5-16.71

.01Sh-.5Sh=-14.21

-.4sh=-14.21

sh=29

Ding ding ding! You win, Daria, and you MUST use the card in my presence :-)!

By the way – my 4th grader isn’t anywhere close to getting this kind of math…

Neither is my 3rd grader. And the teacher didn’t respond to my note asking if he was REALLY expected to be able to do this.

I think the correct answers are:

“No, I am not smarter than a 3rd grader.”

and

“Yes, I’m smarter than a 3rd grader because I know better than to spend time working out the answer to this problem only to earn a $5 Starbucks card.”

…so…since I am right on both counts (no pun intended), do I get the prize???

*SNORT*

You may be the smartest on of all, Debbie!

Good for Daria! I wasn’t even going to try. College Algebra was my first and only F. I learned my lesson then. ðŸ˜‰

Gah, and this is why I will encourage my child to collect bills. Not coins. Bills.

So Starbucks is on me!

Smartypants ðŸ™‚

Aw, I got here too late for the math quiz! That would have been fun! Except I don’t patronize Starbucks.

I can’t believe that’s 3rd grade math…

Hey, I think I made that coffee mug!

Also, is Perlin really a name?

I’ve got coins coming out of my ears. So glad that Daria figured it out, so I could just breathe through it…

Those cause me even more frustration as an adult than they did as a student! You can keep your Starbucks card!!’n

LOL – this was fun – maybe you can make it a weekly series Lori ðŸ™‚

I HATE MATH! And I’m past being able to help my 3rd, 4th, and 5th grader with their homework. I’m lucky I can still help the Kindergarten kid!

I’m not even going to try it, because I know I’m not smarter than a 3rd grader. I gave up helping my daughter with her homework when she was in 3rd grade last year. Math is a whole other animal and taught completely different than when we were kids.

Hrm… Y’know, Starbucks is pretty cool…

But I don’t really feel like trying to figure THAT shenanigan up.

Is your kid in the Talented and Gifted program? Maybe that’s why they’re being given such an insane extra credit assignment.

This makes me glad my kids are out of elementary school, middle school, and high school. I can’t take the pressure ðŸ™‚

i am probably not as smart as a 3rd grader, especially when it comes to math…i zone out on math problems.
