To find out how much money Tina will spend to fill up her car, we first need to determine how much gasoline she needs.

  1. Calculate how much gasoline she needs:

    • Total capacity of the SUV: 18.5 gallons
    • Amount of gasoline currently in the SUV: 4.5 gallons

    \[ \text{Gasoline needed} = \text{Total capacity} - \text{Current amount} = 18.5 \text{ gallons} - 4.5 \text{ gallons} = 14 \text{ gallons} \]

  2. Calculate the cost of the gasoline needed:

    • Cost per gallon: $2.75
    • Amount of gasoline needed: 14 gallons

    \[ \text{Total cost} = \text{Gasoline needed} \times \text{Cost per gallon} = 14 \text{ gallons} \times 2.75 \text{ dollars/gallon} = 38.50 \text{ dollars} \]

Therefore, Tina will spend $38.50 to fill up her car.
