Question

Alex bought some crayon pens and sketch pens in the ratio of 7:4.

Each crayon pen cost $2.

Each sketch pen cost $2 more than each crayon pen.

He spent a total of $360 on these crayon pens and sketch pens.

How much did he spend on the crayon pens he bought?

Answer 1

$168.

Explanation:

1 group of 7 crayon pens and 4 sketch pens = 7 x 2 + 4 x (2 + 2) = 14 + 4 x 4 = $30

Number of groups = 360/30 = 12

12 x 7 x 2 = 168

He spent $168 on the crayons.
