77. Refer to the accompanying cash-flow diagram (see Figure P4-77), and solve for the unknown quantity in Parts

(a) through

(d) that makes the equivalent value of cash outflows equal to the equivalent value of the cash inflow, F. (4.11)

a. If F = $10,000, G = $600, and N = 6, then i = ?

b. If F = $10,000, G = $600, and i = 5% per period, then N = ?

c. If G = $1,000, N = 12, and i = 10% per period, then F = ?

d. If F = $8,000, N = 6, and i = 10% per period, then G = ?
