Question

Alia buys three erasers that cost $0.50 each, two notebooks that cost $5.00 each, and six pencils that cost $0.75 each. Which expression shows how much money Alia spent on supplies?
A. 0.50 + 5 + 0.75
B. 0.50 + 0.50 + 0.50 + 5 + 6(0.75)
C. 3(0.50) + 2(5) + 6(0.75)
D. 3(50) + 2(5) + (75)

Answer 1

The answer is C. because 3(0.50) is $1.50 which equals the erasers price. then two notebooks are $5 each add up to $10. So 2(5). then last 6(0.75) is $4.5 which is the same as the price of six pencils.
