We have a better understanding of the production rates for our Chase-a-Lot toys. Those toys are manufactured in weekly cycles. The machine runs for six days
straight. Over those six days, the machine produces toys at a rate of f(x)=x/20(√3x^2+4
(in thousands of toys per day). After running for six days, the
machine is taken off-line for maintenance on the seventh day, and then the cycle
starts all over again the following week. If each Chase-a-Lot toy requires three
yards of yarn, and there are approximately 350 yards of yarn per skein, how many
skeins of yarn should we order from our supplier each week?
