Question

In 1980, a Domino's large pizza cost $4.99.
What would be the cost of that pizza in 2000?
What would be the cost in 2015?
What would you expect the pizza to cost in 1981?

Answer 1

Answer:

The pizza cost 5.04 in 2000

Step-by-step explanation:

Step One:  set the price of the pizza in 1980 equal to the price in 2000

$4.99              ?

           =  

1980           2000

Step two: Divide 1980 by 2000

1980 / 2000 = 0.99

Step Three: Divide 4.99 by 0.99

Reason: You know that 1980/0.99= 2000 and what ever you do to the denominator you have to do to the numerator and vice versa.

4.99 / 0.99 = 5.0404040

Step Four: Answer

The pizza cost 5.04 in 2000

Keep doing this until you get all of the years (2015 and 1981) pizza prices
