Bot get it right
rental car company charges $28 per day to rent a car and $0.08 for every mile driven. Piper wants to rent a car, knowing that:
She plans to drive 350 miles.
She has at most $140 to spend.
Write and solve an inequality which can be used to determine dd, the number of days Piper can afford to rent while staying within her budget.
Answer
Inequality:
dd
28dd + 0.08(350)dd ≤ 140
Simplify:
28dd + 28dd ≤ 140
56dd ≤ 140
Divide by 56:
dd ≤ 2.5
Therefore, Piper can afford to rent a car for at most 2 days within her budget.
