To find the remaining balance on the card after Alan bought 20 prints, we need to substitute x = 20 into the function B(x) = 25.00 - 0.07x.<br /><br />Substituting x = 20 into the function, we get:<br /><br />B(20) = 25.00 - 0.07(20)<br /><br />Simplifying the expression, we have:<br /><br />B(20) = 25.00 - 1.40<br /><br />B(20) = 23.60<br /><br />Therefore, the remaining balance on the card after Alan bought 20 prints is $23.60.
