Answer:

The first question is A) P + 0.15P + 0.08P

The second question is B) 1.09P

Explanation:

The cost of the dinner is the amount for the dinner, P plus the tax, 8% of P, which is 0.08P, plus the 15% tip, which is 0.15P

The cost of the car is P, or $15, plus the tax is 9%, or 0.09P

P + 0.09P = 1.09P

1st one is A because you wouldn't add them together first and you wouldn't subtract so that gets rid of B, C, and D.

2nd one is B, its really easy because you would just add 0.09 to the 1.00 to get 1.09
