Compare the interest earned on $8,000 for 15 years at 8% simple interest with the amount of interest earned if interest were compounded annually.

Find the present value of the given future payment at the specified interest r $5000 due in 20 years at 5% compounded annually The present value is approximately S (Round to the nearest cent as needed.)

A bank made a farmer a loan of $1,400 at 16% for three years compounded annually. Find the future value and the compound interest paid on the loan. Compare the compound interest with simple interest for the same period. Future value=S (Round to the nearest cent as needed.)

The horizontal axis labeled quantity ranges from 0 to 26 in increments of 2. The vertical axis labeled dollar ranges from 0 to 220 in increments of 20. A line labeled M R begins at the point (0, 200) goes down to the right and ends at the point (10, 0). A second line labeled D begins at the point (0, 200) goes down to the right and ends at the point (20, 0). An upward-facing curve labeled M C begins at the point (3, 85) goes down to the right with decreasing steepness to a low point at (7, 60) then goes up to the right with increasing steepness to end at the point (18, 200). A second upward-facing curve labeled A T C begins at the point (4, 150) goes down to the right with decreasing steepness to a low point at (12, 85) then goes up to the right with increasing steepness to end at the point (21, 160). The curve M C intersects the line M R at (7, 60), the line D at (12, 85) and the curve A T C at (12, 85). All values are approximated."   a. What is the firm’s optimal output?    units…
