Question

Paige was assigned some math problems for homework. She solved the first 32 of the problems before dinner. She finished the last 20% of assignment after dinner. How many math problems was Paige assigned

Answer 1

Well, you know that 32 problems are 80 percent of the total, since she completed 20% of the remaining later.

Answer 2

32 + x = total problems

Answer 3

x = (.2)*total problems

Answer 4

So setup your equation like this:

(0.2)(32 + x) + 32 = 32 + x

that is (20 percent) + (80 percent) = (total)

Answer 5

and solve for x

Answer 6

6.4 + 0.2x + 32 = 32 + x
38.4 + 0.2x = 32 + x
6.4 = 0.8x

x = 8

and what was x? x was 20% of the problems (because 32 was 80%)

Answer 7

so then 32 + 8 = 40 problems total
