Question

While on a business trip to Kensington, Vivian treated her co-workers to a meal that cost

$70. Vivian knew that when the bill came, she would need to pay Kensington sales tax of
10% and would want to leave a 20% tip on the original $70. Including tax and tip, how much did Vivian's meal cost?
$____

Answer 1

$91 because 10% of 70 is $7 and 20% of 70 is $14 so 7+14+70= $91
