Final answer:
The amount of change Christina received from the cashier after buying 8 frozen dinners and 8 pints of ice cream can be calculated by subtracting the total cost of the food from the amount she paid with, which is $100. The correct answer is $33.04.
Step-by-step explanation:
To find out how much change Christina received from the cashier, we need to calculate the total cost of the 8 frozen dinners and 8 pints of ice cream, and subtract it from the $100 bill she paid with.
Total cost of frozen dinners = 8 x $5.12 = $40.96
Total cost of pints of ice cream = 8 x $3.25 = $26.00
Total cost of food = $40.96 + $26.00 = $66.96
Change received from the cashier = $100 - $66.96 = $33.04
Therefore, Christina received $33.04 in change from the cashier. The correct answer is $33.04.
