Question

1. Kim and Cyndi are starting a business tutoring students in math. They rent an office for $400 per month and charge $40 per hour per student. If they have 15 students each for one hour per week how much profit do they make together in a month? (assume 4 weeks per month)

Answer 1

$4400

Explanation:

$40 per hour

15 x 40 = 600

Because 'each' of them had 15 students, 600 x 2 = 1200

There are 4 weeks per month to earn 1200 each week, this is again multiplication.

1200 * 4 weeks = 4800 per month

Out of their earned 4800 they must pay for their overhead, the building rent

4800 - 400 = 4400 profit

They are left with $4400 between them.

Answer 2

$40 per hour
15 students per week
Each hourly student earns them $40 and there are 15 students, so this is multiplication.
40 * 15 = 600 per week
There are 4 weeks per month to earn 600 each week, this is again multiplication.
600 * 4 weeks = 2400 per month
Out of their earned 2400 they must pay for their overhead, the building rent
2400 - 400 = 2000 profit
They are left with $2000 between them.
