PLEASEEE HELPPP question: 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.
