Two car owners are in need of car repairs. Darnel will need to pay the mechanic $10 per hour for labor, plus $20 to cover the cost of new parts. Troy will need to pay $5 for parts and $15 per hour for labor.

Depending on how long each repair takes, the two jobs might end up costing the same amount. How much time would that take, and how much would it cost? Express your answer as an ordered pair (x, y), where the x-axis is the number of hours and the y-axis is the cost.

the correct answer is d

hope this

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
