Answer:
Joshua solved 7 math problems and tread 14 pages.
Step-by-step explanation:
Let x be the number of math problems Joshua solved. The number of pages Joshua read is twice the number of math problems he solved, then 2x is the number of pages Joshua read.
Joshua can solve each math problem in 2.5 minutes, then x math problems he solves in 2.5x minutes.
Joshua can read each page in 3 minutes, then 2x pages he reads in
minutes.
It took him 59.5 minutes to complete all of his homework, so

Solve this equation:

Joshua solved 7 math problems and tread 14 pages.
We conclude that after the discount and the coupon, Will paid $36 for the skateboard.
<h3>
How much did Will pay for the skateboard?</h3>
We know that the original price was $60, and two discounts were applied. One of 20% and other of 25%.
Then the amount that he paid is given by:
P = $60*(1 - 20%/100%)*(1 - 25%/100%)
P = $60*(0.8)*(0.75) = $36
We conclude that after the discount and the coupon, Will paid $36 for the skateboard.
