A rental car company charges $48 per day to rent a car and $0.08 for every mile driven. Bilquis wants to rent a car, knowing that:

She plans to drive 175 miles.
She has at most $110 to spend.

Write and solve an inequality which can be used to determine xx, the number of days Bilquis can afford to rent while staying within her budget.

To determine how many days \( x \) Bilquis can afford to rent a car while staying within her budget, we need to formulate an inequality based on the costs.

The rental car company charges:

  • $48 per day for renting the car
  • $0.08 per mile driven

Bilquis plans to drive 175 miles, so the cost for miles can be calculated as follows: \[ \text{Cost for miles} = 0.08 \times 175 \]

Calculating that: \[ 0.08 \times 175 = 14 \]

Now, let's define the total cost for renting the car. The total cost \( C \) is given by: \[ C = 48x + 14 \] where \( x \) is the number of days she rents the car.

Since Bilquis has at most $110 to spend, we set up the inequality: \[ 48x + 14 \leq 110 \]

Next, we will solve this inequality for \( x \):

  1. Subtract 14 from both sides: \[ 48x \leq 110 - 14 \] \[ 48x \leq 96 \]
  2. Divide both sides by 48: \[ x \leq \frac{96}{48} \] \[ x \leq 2 \]

Thus, the solution to the inequality indicates that Bilquis can afford to rent the car for a maximum of 2 days while staying within her budget of $110.
