A student received a coupon for \( 43 \% \) off the total purchase price at a clothing store. Let b be the original price of the purchase. Use the expression below for the new price of the purchase. Write an equivalent expression by combining like terms. \( b-0.43 \mathrm{~b} \) \( \mathrm{~b}-0.43 \mathrm{~b}=\square \) (Simplify your answer. Use integers or decimals for any numbers in the expression.)

When a student uses a coupon for \( 43\% \) off, it means they only pay for \( 57\% \) of the original price. So we can simplify the expression \( b - 0.43b \) to find the new price. Combining like terms gives us: \[ b - 0.43b = (1 - 0.43)b = 0.57b \] Therefore, the new price of the purchase would be \( 0.57b \). To visualize this, think of it like a delicious pizza! If you have a whole pizza (the original price), and you get to eat \( 57\% \) of it, you’re still left with a satisfying portion (the new price) after accounting for that \( 43\% \) of slices not in your hands. So, you still get a hearty meal!
