Question

Dorian charges his neighbor $8 per hour to walk the dog. His mom pays him $10 to wash her car. Part 1 (2pts): Define a variable (this means to pick a letter to use as your variable for this expression). Explain, in one sentence, why you chose the variable. Part 2 (3pts): Write an expression representing the total amount of money Dorian earns from walking the dog and washing his mom's car.​

Answer 1

Part One: I chose variable t to represent the total amount of money and h to represent each hour of car washing.

Part Two: 8h + 10= t

Explanation:

If, hypothetically, Dorian walked his neighbor's dog for 6 hours throughout the course of the week, we would substitute 6 in place of h. Then solve.

8(6) + 10= t

48+ 10= t

58=t
