Carl wants to buy a television that cost $500 including taxes to pay for the television. He will use a payment plan that requires him to make a down payment of $125 and then pay $72.50 each month for 6 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

x/3-10=8

x/3=18

x=48

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

5050

hope this !
