Acme Company produces two products, A and B$.$ Acme's primary

resource constraint is cloud computing time. Acme sells Product A for

$$41$ per unit and the related variable operating costs are $$13$ per unit. It

takes $3\mathrm{.}5$ minutes of computing time to produce one unit of Product A$.$

Acme sells Product B for $$32$ per unit and the related variable operating

costs are $$17$ per unit. It takes $1\mathrm{.}5$ minutes of computing time to produce

one unit of Product B$.$ Acme has enough capacity to satisfy the demand

for the product with the higher contribution margin but does not have

enough capacity to satisfy the demand for the product with the lower

contribution margin. What is the maximum amount that Acme should

be willing to pay per minute of computing time to acquire additional

capacity?
