Use the formula of the present value of annuity ordinary.
The formula is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value?
PMT payment per month 280
R interest rate 0.018
k compounded monthly 12
T time 4years
Pv=280×((1−(1+0.018÷12)^(−12
×4))÷(0.018÷12))
=12,958.20
It's c
A) x * y = 196A) x = 196 / y
B) x + y = 35Substituting A) into B)
B) 196 / y + y = 35Multiplying both sides by y
B) 196 + y^2 = 35yB) y^2 -35y + 196 = 0
X1 = 28X2 = 7
Put into the formula:
120(1+.08)^5
Equals:
176.3193692 dollars
Answer:
x = 5
Step-by-step explanation:
<u>Step 1: Multiply out the brackets</u>
48x - 80 - 40x + 80 = 40 → <em>negative + negative = positive [-10 x -8]</em>
<u>Step 2: Simplify</u>
8x = 40 →<em> collect like terms</em>
<u>Step 3: Solve</u>
x = 
x = 5
