A small manufacturing plant produces three kinds of bicycles-three-speed, five-speed and ten-speed-in two factories. Factory A produces 16 three-speeds, 12 five-speeds and 30 ten-speeds in one day, while factory B produces 15 three-speeds, 18 five-speeds and 20 ten-speeds in one day. An order is received for 30 three-speeds, 40 five-speeds, and 50 ten-speeds. It costs $1200 a day to operate factory A and $3000 a day to operate factory B. The manufacturer chooses the number of days to operate each factory in order to minimize cost.In the situation above, the variables are
A. x = the total cost to operate factory A y = the total cost to operate factory B B. x = the number of three-speeds produced y = the number of five-speeds produced z = the number of ten-speeds produced C. x = the number of days factory A is operated y = the number of days factory B is operated D. x = the number of days spent producing three-speeds y = the number of days spent producing five-speeds z = the number of days spent producing ten-speeds E. none of these
