Question

a waiter typically receives about 15% of a total food bill as a tip. to earn a total of $50 in tips, about how much food would waiter have to sell

Answer 1

Let x=dollar amount of food waiter has to sell

15%x=$50

0.15x=50

15x=5000

3x=1000 (divide by 5)

x=1000/3

x=$333.33 worth of food

check:15%*$333.33=0.15*333.33=$49.999≈$50.00

Answer 2

$50 = .15x + x, where x is the food bill and .15x is the tip received.

 

50 = 1.15x

 

x = $43.48 (approx.)
