On Tuesday, Jaheim and three of his friends ate dinner at a restaurant where meals cost $12 per person, but are 25% off every Tuesday. The tax on their meal was 8%, and they left a tip that was 20% of the pre-tax price. Note that taxes are calculated based on the discounted cost of the meal before adding a tip, and tips are calculated based on the discounted cost of the meal before adding tax.

Part A. Enter an expression that can be used to find the cost of one person’s meal, not including tax or tip, on a Tuesday.

Part B. How much did the four friends spend in all on dinner? Round your answer to the nearest penny.

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
