Carlos pays $25 for skis and borrows the remaining amount. The loan payments are $75 every 3 months for 1/1/2 years. The interest rate is 16.2%/a compounded quarterly. What was the selling price of the skis?

$417.52

Step-by-step explanation:

Present value of annuity = P * {1-[1/(1+r)^n]/r}

P =Periodic payment i.e. 75

r = rate of interest per period i.e. 16.2% /4 = 4.05% or 0.0405

n =no. of compounding period i.e. 1.50*4 =6

Present value of annuity = Loan amount

Present value of annuity = 75 * {1-[1/(1+0.0405)^6]/0.0405}

Present value of annuity = 75 * {1-[1/(1.0405)^6]/0.0405}

Present value of annuity = 75 * {1-[1/1.268973)/0.0405}

Present value of annuity = 75 * (1-0.78804)/0.0405

Present value of annuity = 75 * (0.21196/0.0405)

Present value of annuity = 75 * 5.23361

Present value of annuity = 392.52

Loan amount = $392.52

Selling price = $392.52 + $25.00

Selling price = $417.52

Thus, the selling price of the skis is $417.52

option: d is correct

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
