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) .
