Using equation, He bought 3 boxes of ballpoint pens and 15 boxes of felt-tip pens
<h3>How to find the boxes of each type of pen using equation?</h3>
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
