!pic attached!Earl and Ray run competing carpet-cleaning services. Earl charges $50 for a house call and $40 per carpet cleaned. Ray charges the same amount per carpet cleaned, but his total cost is always $30 less than Earl's. Which equation expresses the total cost, t, for Ray to

clean as a function of carpets cleaned, c?

t= 20+40c

Step-by-step explanation:

Given that Ray's total cost is always $30 less than Earl's and they charge the same amount per carpet cleaned, the difference is in the amount charged for a house call and to find that amount you have to subtract 30 from the amount Earl's charges:

50-30=20

This means that Ray charges $20 for a house call and $40 per carpet cleaned. According to this, the equation would indicate that the total cost for Ray is equal to the amount he charges for a house call plus the price per carpet cleaned for the number of carpets cleaned, which would be:

t= 20+40c, where:

t is the total cost

c is the number of carpets cleaned
