Answer 1

Answer:

$1200 would be raised if 60 cars were washed.

Step-by-step explanation:

This question can be solved using a rule of three.

The total after 9 cars was of $180. How much would be raised with 60 cars washed?

9 cars - $180

60 cars - $x

Applying cross multiplication

9x = 180*60

9x = 10800

x = 10800/9

x = 1200

$1200 would be raised if 60 cars were washed.
