Question

The conservation club washed 24 cars and earned $144 on Saturday.

At this rate, how much money did they make on Sunday washing 30 cars?

MEDAL,FAN,AND MESSAGE?

Answer 1

proportion time...
24/144 = 30/x --- 24 cars to $144 = 30 cars to $x
cross multiply
(24)(x) = (30)(144)
24x = 4320
x = 4320/24
x = 180

They made $180 for washing 30 cars

Answer 2

or you could do it this way..
24 cars for 144.....144/24 = $6 per car
6 x 30 = 180 ($180 for 30 cars)

Answer 3

thank you omg
