Question

Rafael counted a total of 40 white cars and yellow cars. There were 9 times as Many cars as yellow cars. How Many white cars did Rafael count

Answer 1

Hello.

Let:

w = white cars

y = yellow cars

9 times as many white cars as yellow:

w = 9y         [1]

Total number of cars is 40:

w + y = 40   [2]

Substituting [1] in [2]

9y + y = 40

10y = 40 ⇒ y = 4

Substituting this in [1]

w = 9(4) ⇒ w = 36

36   white cars.

4     yellow cars.

Answer:

36 white cars
