Question

A pencil costs .27 and a pen costs .32. You buy six pencils and the total cost is 4.18 How many pens did you buy?

Answer 1

8 pens

Explanation:

Finding the number of pens bought

pencil costs 0.27

pen costs 0.32

6 * pencils + x pens = 4.18

6 * 0.27 + x * 0.32 = 4.18

1.62 + 0.32x = 4.18

0.32x = 4.18 - 1.62

0.32x = 2.56

x = 2.56/0.32

x = 8

hence 8 pens were bought
