Erin earns $7.50 for each hour she works. Rita earns $9.00 for each hour she works.

arsen [322]

Total earnings of Rita($360) is greater then that of Erin($300) .

<u>Step-by-step explanation:</u>

Here we have , Erin earns $7.50 for each hour she works. Rita earns $9.00 for each hour she works. The table shows the amounts that Erin and Rita earn for working 1 to 6 hours.

Hours Erin Rita

1 $7.50 $9.00

2 $15.00=7.50(2) $18.00 =9(2)

3 $22.50=7.50(3) $27.00 =9(3)

4 $30.00=7.50(4) $36.00 =9(4)

5 $37.50=7.50(5) $45.00 =9(5)

6 $45.00=7.50(6) $54.00 =9(6)

From the tale we can clearly see that , General formula for Erin working hours is :

⇒ $7.50(n)$ where n is number of hours worked And ,

General formula for Rita working hours is :

⇒ $9(n)$ where n is number of hours worked

So , for 40 hours work total earnings of Erin & Rita is $7.5(40) = 300$ and $9(40) = 360$ respectively. Therefore , Total earnings of Rita($360) is greater then that of Erin($300) .
