The profit made when t units are sold, t>, is given by Pē-36t+320. Determine the number of units to be sold in order for P>0 (a profit is made).

The future value of $6000 invested for 5 years at rate r, compounded annually, is given by S=6000(1+r)^5. Find the rate r, as a percent that gives a future value of $8415.31. Round to the nearest whole percent.

**Henry**, Thursday, July 7, 2011 at 8:38pmS = 6000(1+r)^5 = $8415.31,

(1+r)^5 = 8415.31 / 6000 = 1.40255,

Take log of both sides:

5log(1+r) = log1.40255 = 0.1469,

log(1+r) = 0.1469 / 5 = 0.02938,

1+r = 10^0.02938

1+r = 1.06998,

r = 0.06998 = 6.998% = 7%.
