Answer:
26 feet
Step-by-step explanation:
w: width
w+4 : length
w(w+4) = 572
w² + 4w - 572 = 0
w² + 26w - 22w - 572 = 0
w(w+26) - 22(w+26) = 0
(w-22)(w+26) = 0
w = 22, -26
width = 22 feet
length = w+4 = 22+4 = 26 feet
To get the effective interest rate (EIR) of the loan, determine first whether we will use a simple interest method or a discounted method. In this case, we will use a discounted method because the loan is a discounted one. In a discounted method, interest is deducted from the loan principal. So the formula will look like this:
EIR = Interest ÷ (Principal - Interest)
Before proceeding any further, solve first for interest. (assuming a 360-day year)
Interest = Principal × rate × interest
= $2950 × (100/360) × (0.085)
= $69.65
Thus, EIR can be computed as follows:
EIR = ($69.65 ÷ ($2950 - $69.65)) × 360
≈ 8.7%
Notice that the EIR was multiplied by 360 to return it to an annual rate.
