Question

Estimate a 15% tip on a dinner bill of $31.81 by first rounding the bill amount to the nearest ten dollars

Answer 1

Answer: $36.60

Explanation:

Convert 15% to decimals. You can do this by dividing by 100.

`(15)/(100)=0.15`

Now calculate 15% of 31.81 (0.15*31.81)

$4.77

if you add it to the bill you get 31.81+4.77=36.58

it says round to the nearest ten dollars=36.60
