Question

Over the past month, 900 trucks were sold. Abe sold 4 times as many as Joe. How many did each sell?A. Number of trucks Abe sold.

Answer 1

Let us assume that the number of trucks Joe sold is x.

If Abe sells 4 times as many trucks as Joe does, this means that Abe sells

$4\times x=4x\text{ trucks}$

There were 900 trucks sold. Thus adding up the number of trucks both Abe and Joe sells will give us 900:

$4x+x=900$

Solving the expression, we can get the value for x to be

$\begin{gathered} 5x=900 \\ x=\frac{900}{5} \\ x=180 \end{gathered}$

Therefore, Joe sold 180 trucks.

The number of trucks sold by Abe will also be calculated as

$4\times180=720$

Therefore, Abe sold 720 trucks.
