Answer 1

$2680

Explanation:

A certain Math Club makes 35 bars of laundry soap a week and sells these at $20 each.

For 1 week

= $35 × 20

= $700.

For 4 weeks =

4 × $700 = $2800

Before the soap can all be sold, the pupils found out that 6 bars were destroyed by mice.

Hence, the amount lost = $20 × 6

= $120

How much will be the total sale at the end of a four-week month?

The total sale =

$2800 - $120

= $2680
