Question

Lisa purchased a hat for $10, a purse for $20, and a book for $23. The sales tax rate was 7.2 percent. What was the total amount she paid? $0.53 $3.82 $53 $56.82

Answer 1

10+20+23 is 53. A sales tax of 7.2% is $3.82. 53+3.82 is $56.82

Answer 2

She paid $ 56.82.

Explanation:

Since, the cost of one hat = $ 10,

One purse = $ 20,

One book = $ 23,

Thus, the original cost of all item that are bought = 10 + 20 + 23 = $ 53,

Given,

The sales tax = 7.2 %,

Hence, the total amount she paid = The original cost of all item + 7.2 % of the original cost of all item

`=53+(53* 7.2)/(100)`

`=53 + (381.6)/(100)`

`=53 + 3.816=\$56.816\approx \$56.82`
