High School

Ricki is working a part-time job this summer. The table shows how many hours she worked each day during her first week:

- Monday: 4 hours
- Tuesday: 0 hours
- Wednesday: 5 hours
- Thursday: 5 hours
- Friday: 0 hours
- Saturday: 3 hours
- Sunday: 3 hours

This week is representative of how many hours Ricki will work each week during the summer. If she earns $9 per hour and there are 12 weeks during her summer, what will Ricki’s gross earnings be? Explain your reasoning.

Answer :

Answer:

$2160

Step-by-step explanation:

total hours worked: 20

therefore 20hours×12weeks=240 hours in 12 weeks

240hrs×$9.00 per hr= $2160

She will earn $2160 in 12 weeks.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Ricki work = 4+5+5+3+3= 20 hours

For 12 weeks she works

= 12 x 20

= 240 hours

If she earns = $9 in one week

So, She will earn

= 240 x 9

= $2160 in 12 weeks.
