Mr. Alter found a t-shirt at Kohl’s for a ticketed price of $24. He had a coupon for 20% off. The sales tax rate was 8%. How much did the t-shirt cost? Please round your answer to the nearest cent. p

$20.74     you can round

Step-by-step explanation:

First you can see he has a shirt that is $24 and he had a coupon for 20% off!

The first step is to figure out 20% off of $24!!!

Well I just use a percent calculator off online!!

I came up with $19.20 with the coupon!!

Then 8% tax rate added to $19.20 is $20.74!

That is how I figured out my answer!!

Sorry if I did not show all the step by step and how to figure out the coupon or the tax!

The answer is $20.74 not rounded!!!

step-by-step explanation:

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
