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 \( \text{\$} 39.35 \).
