A video game originally cost 49.99.it was discounted15%. What is the sale price of the game

$42.49

Step-by-step explanation:

s=p−(p×d)

Where:

s

is the sales price: what we are solving for in this problem

p

is the original price: $49.99 for this problem

d

is the discount percent: 15% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 15% can be written as

15/100. Substituting and calculating

s gives: s =$49.99-($49.99×1510)

s=$49.99−$749.8100

s=$49.99−$7.4985   s=$42.4915    s=$42.49

rounded to the nearest cent.

The sales price of the video game is $42.49

42.49

Step-by-step explanation:

49.99 × 15% = 7.50

49.99 - 7.50 = 42.49

The sale price is 42.49.

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
