Q. The expression 1.16(0.75p) 1.16(0.75 p) represents the amount Aubrey paid for dinner at a restaurant after she applied a discount coupon and added tip. Which changes to the original price could have resulted in the expression?\newline116% 116 \% tip and then a discount of 75% 75 \% \newline0.16% 0.16 \% tip and then a discount of 75% 75 \% \newlineA discount of 75% 75 \% and then 16% 16 \% tip\newlineA discount of 25% 25 \% and then 16% 16 \% tip
  1. Understand the expression: Understand the expression 1.16(0.75p)1.16(0.75p). This expression represents two consecutive changes to the original price pp. The first change is represented by 0.75p0.75p, which suggests a reduction to 75%75\% of the original price, indicating a 25%25\% discount. The second change is represented by multiplying the discounted price by 1.161.16, which suggests adding a 16%16\% tip to the discounted price.
  2. Analyze first option: Analyze the first option, "116116% tip and then a discount of 7575%." This would mean applying a 116%116\% tip on the original price and then reducing the resulting amount by 75%75\%. The expression for this would be (1+1.16)p×0.75(1 + 1.16)p \times 0.75, which simplifies to 2.16p×0.752.16p \times 0.75. This is not the same as the given expression 1.16(0.75p)1.16(0.75p).
  3. Analyze second option: Analyze the second option, "0.16%0.16\% tip and then a discount of 75%75\%." This would mean applying a 0.16%0.16\% tip on the original price and then reducing the resulting amount by 75%75\%. The expression for this would be (1+0.0016)p×0.75(1 + 0.0016)p \times 0.75, which simplifies to 1.0016p×0.751.0016p \times 0.75. This is not the same as the given expression 1.16(0.75p)1.16(0.75p).
  4. Analyze third option: Analyze the third option, "A discount of 7575% and then 1616% tip." This would mean reducing the original price by 75%75\% and then adding a 16%16\% tip to the discounted price. The expression for this would be 0.75p×1.160.75p \times 1.16, which simplifies to 1.16(0.75p)1.16(0.75p). This matches the given expression.
  5. Analyze fourth option: Analyze the fourth option, "A discount of 25%25\% and then 16%16\% tip." This would mean reducing the original price by 25%25\% (making it 75%75\% of the original price) and then adding a 16%16\% tip to the discounted price. The expression for this would be 0.75p×1.160.75p \times 1.16, which simplifies to 1.16(0.75p)1.16(0.75p). This also matches the given expression.
