Part I. Basic Computations 1. A discount store sold plastic cups for $3.25 each and ceramic cups for $4.50 each. a. If 500 cups were sold for a total of $2,090, how many cups of each type were sold? (5 points) Answer: p + c = 500 cups 3.25p + 4.5c = $2090 325p + 325c = 325*500 325p + 450c = 209000 Ceramic 372 Plastic 128 b. What was the dollar value of each type of cup sold? (5 points) Answer: 2. LaToya Smith is a buyer for a large manufacturing company . She can purchase 200 pounds of chemicals for $95. She can also purchase mixing vats for $400 each.

( 5 points) Answer: 4,000 pounds divided by 200 pounds is 20 200 pounds = $95  $95 X 20= $1900 $1900 X 6% tax= $2014 $2014 + $30 shipping = $2044 b. This month she doesnt know yet how many mixing vats she will need to order. Let y = number of mixing vats required.
