Answer:
In 14 weeks, they will have the same earnings.
Step-by-step explanation:
y = 55x + 1300 -------- (1)
y = 25x + 1720 -------- (2)
(2) = (1)
55x + 1300 = 25x +1720
55x - 25x = 1720 - 1300
30x = 420
30x ÷ 30 = 420 ÷ 30
x = 14
Look at the ratio (2:3). You can see that the numbers of "ratio units" add up to 5, and that the total number of books is 100 times that value. Then each "ratio unit" stands for 100 books.
3 ratio units of chapter books mean there are 300 chapter books.

1. 0.25x + 15 = 0.05x + 20
0.20x = 5
x = 25
2. 1/3x = x-22
-2/3x = -22
x = 33
