Carrie buys 4.16 pounds of apples for 5.20 how much does 1 pound cost
JulijaS [17]
4.16 / 5.20 = 1 / x.....4.16 lbs to $ 5.20 = 1 lb to $x
cross multiply because this is a proportion
(4.16)(x) = (5.20)(1)
4.16x = 5.20
x = 5.20 / 4.16
x = 1.25 per lb <==

The following refers to a purchase of a machine by a company on January 1, 2016
grandymaker [24]

The semi-annual net cash flow the company must achieve in order for the purchase to be made is $2500.

<h3>How to calculate the cash flow?</h3>

Number of period = 6 × 2 = 12

Rate = 4% / 2 = 2%

Annual cash flow × PVIFA × (2% × 12) + $7500 × PVIF(2%,12) - $32348 = 0

Annual cash flow × 10.5753 = $32348 - $7500 × 0.7885

Annual cash flow × 10.5753 = $32348 - $5914

Annual cash flow × 10.5753 = $26434

Annual cash flow = 26434/10.5753

Annual cash flow = $2500
