In 1992, Jason bought a gallon of gas for $1.20. Yesterday, he bought a gallon of gas for $2.22. What is the percentage increase of the price of a gallon of gas from 1992 to yesterday? If necessary, round to the nearest tenth of a percent. A.
54.1%
B.
15%
C.
45.9%
D.
85%

A.

Step-by-step explanation:

(I'm not sure if this is right so let me know)

If you divide 1.20 by 2.22 it comes out as 0.5405. If you take this and round, you get 0.541. After this, to make it a percentage, you move the decimal 2 places left, which comes out as 54.1%

Hope this helps!

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
