54, 36, 24 are the 1st 3 element of a geometric progression with 2/3 as a common ratio: PROOF:
the 1st term is 54, (a₁= 54) the 2nd term a₂ = 24, then
(a₂ = a₁.r) or 36 = 54.r → r= 36/54 = 2/3. Same logique for the 3rd term.
So 2/3 is common ratio. We know that :U(n) = a.(r)ⁿ⁻¹. Then if a =54 and r = x (given by the problem), then f(x) = 54.xⁿ⁻¹
n, being the rank of any element of this geometric progression

Answer:
a dry-erase maker
Step-by-step explanation:
Answer:
19
Step-by-step explanation:
First, find the unit rate. (How much she makes in 1 hour.)
28.50/3 is 9.5
Now it asks for how much she will make in 2 hours.
9.5 x 2 is
19.
