A man ordered 5 times as many boxes of ballpoint pens as boxes of felt-tip pens. Ballpoint pens cost $4.33 per box, and felt-point pens cost $3.42. If the man’s order of pens totaled $75.21, how many boxes of each type of pen did he buy

Respuesta :

Using equation, He bought 3 boxes of ballpoint pens and 15  boxes of felt-tip pens

How to find the boxes of each type of pen using equation?

let

x = number of boxes of ballpoint pens

y = number of boxes of felt-tip pens

Therefore, the situation will form an equation.

x = 5y

Hence,

4.33x + 3.42y = 75.21,

4.33(5y) +  3.42y = 75.21

21.65y + 3.42y = 75.21

25.07y = 75.21

y = 75.21 / 25.07

y = 3

x = 5(3) = 15

Hence, he bought 3 boxes of ballpoint pens and 15  boxes of felt-tip pens
