Question

Charlene bought her friends lunch. The bill came to $52.80 before Charlene added an 18% service tip. How much did she add for the service tip?

Answer 1

$9.50 because $52.80 time 1.18 gives you $62.30 so when you subtracts $52.80 from that you get your answer.

Answer 2

$9.50
52.80 * .18 = 9.50
