Question

Since school started, Billy has read 14 pages per night, on average. That is 40% more pages

than he averaged over the summer. How many pages per night did Billy average during the
summer?

Answer 1

Billy averaged 10 pages per night during the summer, calculated by reversing the 40% increase to his school year average of 14 pages a night.

Step-by-step explanation:

The student is asking a question related to mathematical percentage calculations. Billy has read 14 pages per night, on average, during the school year. This is stated to be 40% more than his summer reading average. To find out how many pages he read on average each night during the summer, we can set up the equation where summer average plus 40% of that summer average equals 14 pages.

Let's denote summer average as x. The equation is: x + 0.40x = 14. Simplifying, we get 1.40x = 14. When we divide both sides of the equation by 1.40, we find x, which equals 10.

Therefore, Billy averaged reading 10 pages per night during the summer.
