hayden delivers pizza for papa john's. His average tip is $1.50 for each pizza that he delivers. How many pizzas must he deliver to earn at least $20 in tips?

Respuesta :

14 pizzas, you will get $20.50

let us assume that the number of pizzas he must deliver = x

The tip obtained for one pizza = $1.50

Total tips that he must earn = 20

So, we frame the equation as shown below:

1.50*x = 20

1.50x = 20

x = 20/1.5 = 13.333

So he must deliver 13.333 pizzas

Since he cannot deliver fractional pizzas, the number of pizzas he must deliver = 14 pizzas
