PLEASE HELP ASAP

Answer 1

Answer:

see below

Step-by-step explanation:

Let y = the total cleaning cost

Let x = the number of roots cleaned.

Therefore, if the cost is $22 per room,  y = 22x

200 = 22x

Divide both sides by 22:  9 $\frac{2}{22}$ = x

Therefore, 9 rooms can be cleaned for $200

New equation:  y = 22x + 40

200 = 22x + 40

Subtract 40 from each side:  160 = 22x

Divide both sides by 22:  7 $\frac{6}{22}$ = x

Therefore, 7 rooms can be cleaned for $200 if the carpet cleaners receive a $40 tip
