The Gomez family ordered $39.50 worth of
pizza and subs. They gave the delivery person
a 20% tip. What was the total cost of the food
and tip? Roun to the nearest cent?

Respuesta :

Step-by-step explanation:

To find the cost of the tip, we need to find 120% of 39.50.

120% = 100% (order) + 20% (tip)

Let's use fractions. 39.50 can be put over 1, and 120 can be put over 100.

Equation:

[tex]\frac{39.50}{1} \times \frac{120}{100} =?[/tex]

Multiply:

[tex]\frac{39.50}{1} \times \frac{120}{100} =\frac{4740}{100}[/tex]

Divide 4740 and 100 by 100:

[tex]\frac{4740 \div 100}{100 \div 100} = \frac{47.4}{1}[/tex]

The total cost of the food is $47.40.
