Danielle, her husband and son go out to dinner. the subtotal (before tax) is $53.40. if sales tak is 6.5% and they want to leave a 20% tip, how much money will they end up paying their waitress?

Step 1: find the sales tax:

To find 6.5% of $53.40, divide 6.5 by 100 to make it 0.065, then multiply it by $53.40 to get $3.47

Step 2: find the tip

To find 20% of $53.40, first divide 20% by 100 to get 0.20, then multiply it by $53.40 to get $10.68

Step 3: add it all up

$53.40 + $3.47 + $10.68 = $67.55
