Answer:
A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers.
9r - 6 = 8r + 3
r = 9
EF = 4r + 19 = 4(9) + 19 = 36 + 19 = 55

There are 10 single-digits (0 through 9) and 26 letters (A through Z)
For the first slot there are 10 choices which represents selecting a single digit
For the second slot there are 26 choices because we choose a single letter here.
Finally there are another 10 choices for the third slot (assuming repeats are allowed)
Multiply the values out: 10*26*10 = 260*10 = 2600
Answer: 2600
3/4 of $60 = $45 for the coat
60 - 45 = $15 left
1/2 of $15 = $7.50 for the skirt
15 - 7.50 = $7.50 left
