Answer:

The answer is C

Pay attention, here's why.

Step-by-step explanation:

Let's solve your equation.

−7x+6=27

Step 1: Subtract 6 from both sides.

−7x+6−6=27−6

−7x=21

Step 2: Divide both sides by -7.

−7x /−7 = 21/ −7

x=-3

Answer:

$9000

Step-by-step explanation:

Given

Monthly payment P = $300
Time t = 3 years = 36 months
Number of payments n = 36
Interest rate r = 12% PA = 1% per month = 0.01 times

Use loan payment formula:

P = r(PV) / (1 - (1 + r)⁻ⁿ),
where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of payments

Substitute values and solve for PV:

300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)
PV = 300*(1 - 1.01⁻³⁶ )/ 0.01
PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)
