Question

Anna works at Office Max Markers cost $1.50 each and pens cost $1.00 each. One day she sold a total of 50 pens and markers for $65.00. How many markers did Anna sell?

Answer 1

`x = 30`

Explanation:

Let `x` be the number of markers sold.
Since Anna sold a total of 50 items, the number of pens sold is `50 - x`

`1.50x + 1(50 -x) = 65`

`=> 1.50x + 50 - x = 65`
`=> 0.50x = 15`
`=> x = 30`
