Touchie MacFeelie's production function is 0.1J1/2L3/4 where J is the number of old jokes used and L is the number of hours of cartoonist's labour. He is stuck with 900 old jokes for which he paid $6 each.
A) If the wage rate for cartoonists is $5 per hour, then what is the toal cost of producing 24 comic books is?
B) Suppose that Touchie can vary both jokes ad cartoonists' labour. If old jokes cost $2 each and cartoonists' labour costs $18 per hour, then the cheapest way to produce comic books requires using jokes ad labour in the ratio J/L=?
