Over the past month, 900 trucks were sold. Abe sold 4 times as many as joe. ?

let X be the number of trucks Joe sold, so, we have

X + 4X = 900

(the number of trucks sold by Joe plus the number of trucks sold by Abe, is the total amount of trucks sold), now, solve for X

5X = 900

X = 180

Let's go back, we let X be the number of trucks Joe sold, so, Joe sold 180 trucks. Abe sold 4 times as many, so 4X

4X = 4(180) = 720

that means Abe sold 720 trucks

finally, let's check our answer to make sure the total is 900

180 + 720 = 900

our answer is right

I hope this helped you

Suppose that Joe sold x trucks

Abe sold 4x trucks

4x + x = 900

5x = 90

x = 180.

Joe sold 180, Abe sold 720.
