ACT Math Problems Thread

So I decided to start a thread for ACT math problems let’s see how this goes…

Here’s one I came across that I got wrong if someone could explain that would be great!

Mr. Wilk is a high school math teacher whose salary is $33,660 for this school year, which has 180 days. In Mr. Wilk’s school district, substitute teachers are paid $85 per day. If Mr. Wilk takes a day off without pay and a substitute teacher is paid to teach his classes, how much less does the school district pay in salary by paying a substitute teacher instead of Mr. Wilk for that day?

doing straight math, I get $102. BUT, the question is vague…a salary is usually an annual thing based on 365 days not 180. was there an explanation for the answer?

3

It is $102, there was no explanation @rofikicafe

Reggie knows how to make 5 different entrees, 4 different side dishes and 6 desserts. How many distinct complete meals, each consisting of an entrée, a side dish, and a dessert, can Reggie make?

5

Here’s the explanation for the answer of $102:

If his annual salary is based on 180 days, he earns 33660/180 or $187 per day… they save that much if he’s taking an unpaid day off.
They pay the sub $85. Subtract the two and you get $102

For Reggie, it’s the simple Counting Principle: 5x4x6= 120 meals

After a snowstorm, city workers removed an estimated 12,000 cubic meters of snow from the downtown area. If the snow were spread in an even layer over an empty lot with dimensions 62 meters by 85 meters, about how many meters deep would the layer of snow be?

8

oh sorry…I see someone did the explanation. I was wondering if it was a trick question.

9

For the snowstorm question: find the volume of the lot and set it equal to the amount of snow:
62(85)(x) = 12,000
5270x = 12000
x=2.2770398 meters-- not sure how you’re supposed to round. It says “about” so they’re hinting that it won’t be a round number.

Shannon walked 1 2/3 miles on Wednesday and 2 3/5 miles on Thursday. What was the total distance, in miles, Shannon walked during those 2 days?

11

Wait, you’re seriously asking how to add two mixed numbers in preparation for college? After asking how to find the volume of a rectangular solid and the Counting Principle?

Can I ask what grade you’re in?

12

@bjkmom I know how to do the problem…I’m posting for other people if they don’t understand…I’m going to stop posting on this thread

13

This thread was made to help other people who needed help with math problems

14

I guess I misunderstood.

No need for you to leave. But I think I’ll take a leave of absence from it.

If you already knew the answers, why didn’t you post the solution and the explanation?
If someone has this type of gap for the ACT math, the person will benefit from a tutor or a course in algebra.
