Question

Reba went out to eat dinner. She spent $8.25 on food, and tax was 7.4%. How much total money did Reba spend, including dinner and tax?

A) $8.90
B) $8.89
C) $9.00
D) $8.81

Answer 1

To find the total cost including tax, we multiplied the meal cost by the tax rate, converted to a decimal, to get the tax amount, then added it to the meal cost. The closest answer to our calculated total of $8.86 is option B) $8.89.

Step-by-step explanation:

To calculate the total amount Reba spent on dinner including tax, we need to calculate the value of the tax and add it to the original cost of the meal. To find the amount of tax, we convert the percentage to a decimal by dividing by 100 and then multiply by the cost of the meal. In Reba's case, the tax rate is 7.4%, so we convert that to a decimal (0.074) and multiply it by the cost of the food, $8.25.

The calculation for the tax amount will be: $8.25 × 0.074 = $0.6105. When rounded to the nearest cent, this becomes $0.61. To find the total cost including tax, we then add the tax to the original cost of the food: $8.25 + $0.61 = $8.86.

Among the given choices, the correct total cost, rounded to the nearest cent, does not exactly match any option, so it seems there might be a typo in the provided options. However, if we were to choose the option closest to our calculated total, it would be (choice B) $8.89.
