Brian received a \( \$ 40.75 \) gift card for a photo center. He used it to buy prints that cost 7 cents each. The remaining balance, \( B \) (in dollars), on the card after buying \( x \) prints is given by the following. \[ B=40.75-0.07 x \] What is the remaining balance on the card if Brian bought 20 prints? dollars

To find the remaining balance on the card after Brian bought 20 prints, we can substitute \( x = 20 \) into the equation for \( B \): \[ B = 40.75 - 0.07 \times 20 \] Calculating the cost of 20 prints: \[ 0.07 \times 20 = 1.4 \] Now, substitute this back into the equation for \( B \): \[ B = 40.75 - 1.4 = 39.35 \] So, the remaining balance on the card after Brian bought 20 prints is \( \text{\$} 39.35 \).
