. The rate of discount R, can be determined using the formula R = 1 – P-D over P, where P is the regular price of an item and D is the discount, or amount saved off the regular price. Find the rate of discount on a sweater with a regular price of $28.99 that is on sale for $10.99.

Use the combination formula to figure out the first problem. nCr = n!/(r!(n-r)!)
 r = 7, n = 11
nCr = 11!/(7!*4!)
nCr = 330
