Question

Louisa paid $12.25 for books at a yard sale she spent $2.50 on a hardcover book and the rest on 13 softcover books each of the softcover books cost the same. What was the cost of a single softcover book. Write and solve an equivalent equation

Answer 1

Set up the equation:

12.25 = 2.50 + 13x

x represents the price of the softcover books. 

Subtract 2.50 from both sides to get:

9.75 = 13x

Then, divide both sides by 13:

0.75 = x

So, one softcover book cost $0.75
Hope this helped!! xx
