Businesses can buy multiple licenses for a data-compression software at a total cost of approximately

Question

C(x) = 72x^2/3 dollars for x licenses. Use a calculator to find the actual cost of the 64th license by evaluating C(64) − C(63)
for the cost function. (Round your answer to two decimal places.)

Answer 1

For this question we can plug in our values for 63 and 64 to obtain:

 

C(64)-C(63) = 72(64^2/3) - 72(63^2/3), which we use a calculator to plug in this computation 

=12.03
