Answer 2

Answer:

1 hour.

Step-by-step explanation:

Mari has a part time job.

She earns $7 per hour.

She makes at most $13.20 per week.

1 hour gives $7

How many hours gives $13.20 ?

Cross multiplying gives;

$\frac{13.20}{7}$ × 1 hour = 1.885714286 hours

Since she can't get a payment for 0.885714286 hours, she will have to work for 1 hour.
