Answer:
Alicia spent $12 on each book.
Explanation:
What we know:
- In the beginning, Alicia had $94
- She bought 7 books, that each cost the same price
- After buying the 7 books, she had $10 left over.
What we need to find:
- The cost of an individual book
Steps:
1. To find how much money she spent in total, we must subtract the leftover amount of money ($10) from the amount of money Alicia started with ($94).
94 - 10 = 84
2. Now, we have to figure out how much money Alicia spent on each book. We know that she spent a total of $84. We need to divide that amount by 7 to find the amount that Alicia spent on one book.
84 ÷ 7 = 12
Check your work:
1. Multiply the cost of one book by the number of books Alicia bought.
12 x 7 = 84
2. Find the sum of the amount Alicia spent and the amount of money Alicia had left over. 84 + 10 = 94
The total amount of money Alicia started with was $94, so we can conclude that Alicia did indeed spend $12 on each book.
