Suppose Skyler invests in an annuity that pays 3.2% annual interest, compounded monthly. If she contributes $155 every month for 10 years, how much interest would she earn during that time? Round your answer to the nearest cent. Do NOT round until you have calculated the final answer.

$3286.47

Step-by-step explanation:

155((1+0.032/12)^12*10

          0.032/12

P_10 = 21886.46638739

155 * 12 * 10 = 18600

21886.46638739 = 18600 + I_10

I_10 = 3286.46638739

round answer to nearest cent

$3286.47

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
