Jennifer bought a brand new treadmill on a credit plan at befit exercise equipment. befit will charge her 15% per year compounded monthly. if her monthly payments will be $150 for 4 years, how much was the original price of the treadmill?
a) $5,390.72
b) $5,389.72
c) $5,388.72
d) $5,392.72
e) $5,385.72

$ 5,389.72

Step-by-step explanation:

This is an annuity question.

Using the formula:

P = E [ ]

E = $150

i = 0.15/12 , since it is compounded monthly

ans P is the original price

substituting into the formula , we have

P = 150 [ ]

P =  150 [ ]

P = 150 [ ]

P = 150 [ 35.93148088]

P = $ 5,389.72

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
