Answer:
A
Step-by-step explanation:
Pick a letter that's easy to count. I chose Q, because it has a tail below the baseline that makes them easy to spot.
Not C or D — too many quarters
Not B — too many nickels
It is often easier to find the correct answer choice by eliminating the bad choices, then seeing if what is left is consistent with the problem statement.
Choice A seems to have the right numbers of pennies and dimes (along with quarters and nickels).

Answer:
There are 1,892,800,000 different standard plates that are possible in this system
Step-by-step explanation:
The plates follow the following format:
D - D - L - L - L - D - D - D
For each digit there are 10 possible outcomes, and for each letter there are 26 possible outcomes.
So, there are
10*10*26*26*28*10*10*10 = 1,892,800,000
different standard plates that are possible in this system
I am assuming that the cost of an oil change already includes the mark-up.
So, 18 is 175%. 18 ÷ 1.75 = 10.29 is the original cost.
10.29 * 3/4 = 30.87/4 = 7.71 mark-up
10.29 + 7.71 = 18
Or if 18 is the basis of the mark-up, then,
18 * 3/4 = 54/4 = 13.50 mark-up
18 + 13.50 = 31.50 new cost of an oil change
