Question

Jasmine bought a calendar and a book for a total of $24. The calendar cost $10. Which equation can be used to find b, the cost of the book?

b-10=24
b-24=10
b+10=24
b+24=10

Answer 1

Adding the price of the book to the price of the calendar to equal the total amount would be the equation to use.

b+10=24

Answer 2

b+10=24

Explanation:

The total cost is equal to the cost of the book plus the cost of the calendar

The total cost is 24, the cost of the book is b and the cost of the calendar is 10

24 = b+10

or b+10 = 24
