Question

There are pens on sale for 3 pens for 6 dollars. Sasha bought 3 pens. Malachi bought 1 pen. How much more did Sasha spend than Malachi?

Answer 1

Sasha spent 4 dollars more each pen costs 2 dollars.
6÷3 = 2

Answer 2

Sasha spent $4 more than Malachi.

Explanation:

Pens are selling at the rate of 3 pens for 6 dollars.

Therefore, cost of one pen =
`(6)/(3)`

= $2

Now Sasha bought 3 pens so the cost of 3 pens = 3×2 = $6

Malachi bought 1 pen so Malachi spent for one pen = $2

Difference between Sasha and Malachi expenditure = $6 - $2

= $4

Therefore, Sasha spent $4 more than Malachi.
