the prime factorization of 140 is 2^2 x 5 x 7

the prime factorization of 80 is 2^3 x 5 x 2

Part A: $27.32

Part B: $32.24

Step-by-step explanation:

Part A:

$25.30 is the cost, since we are increasing it by the 8% meals tax, we are going to do 25.3 * the decimal form of 8%, or 0.08, plus one so that we already have our 25.3 factored in. Which equals 25.3 * 1.08, which equals 27.324, which we round to $27.32.

Part B:

We take our $27.32 and we times it by 1.18 for the reason stated above, which equals 32.2376, which is rounded to $32.24.
