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)

General formula for Rita working hours is :
⇒ where n is number of hours worked
So , for 40 hours work total earnings of Erin & Rita is and
respectively. Therefore , Total earnings of Rita($360) is greater then that of Erin($300) .
