Meredith ordered 2 dozen donuts for a party.
2 of the donuts were blueberry,
5and the rest were glazed. The blueberry donuts cost $0.75 each, and the glazed donuts cost $1.25 each.
Which expression represents the total cost of the donuts?
Responses
A
24[( 2 )(0.75) × 3 (1.25)]
5 5 24[( 2 )(0.75) × 3 (1.25)] 5 5
B
24[( 2 )(0.75) - 3 (1.25)]
5 5 24[( 2 )(0.75) - 3 (1.25)] 5 5
C
24[( 2 )(0.75) + 3 (1.25)]
5 5 24[( 2 )(0.75) + 3 (1.25)] 5 5
D
24[( 2 )(0.75) ÷ 3 (1.25)]
5 5
The correct expression is C: 24[(2)(0.75) + 3(1.25)].
The correct expression that represents the total cost of the donuts is:
C) 24[(2)(0.75) + 3(1.25)]
To find the total cost of the donuts, we need to add the cost of the blueberry donuts and the cost of the glazed donuts.
The cost of each blueberry donut is $0.75, and there are 2 blueberry donuts:
2(0.75) = $1.50
The cost of each glazed donut is $1.25, and there are 24 donuts in total, but 2 of them are blueberry:
Remaining glazed donuts = 24 - 2 = 22 donuts
22(1.25) = $27.50
Now we can find the total cost by adding the cost of the blueberry donuts to the cost of the glazed donuts:
Total cost = $1.50 + $27.50 = $29.00
Looking at the options provided, the expression that represents the total cost of the donuts is:
C. 24[(2)(0.75) + 3(1.25)]
