Given revenue and cost functions R(q)=80q0.5q2 and C(q)=13q+550, find the maximum profit that can be earned by selling this product. The maximum profit is $ (Round to nearest integer.) Given revenue and cost functions R(q)=80q0.4q2 and C(q)=13q+600, find the maximum revenue that can be earned by selling this product. The maximum revenue is $ (Round to nearest cent.) The marginal profit is $ per item. (Round to two decimal places.) Given revenue and cost functions R(q)=70q0.5q2 and C(q)=15q+550, find the quantity when profit is maximized. The quantity is items. (Round answer to nearest item.) Given revenue and cost functions R(q)=90q0.4q2 and C(q)=15q+500, find the quantity that maximizes revenue. The quantity is (Round to nearest integer.) Given Cost and Revenue functions C(q)=q38q2+53q+5000 and R(q)=3q2+2600q, what cosis should the compary expect to cover if it maximizes profit? The costs would bes (Round to nearest cent)
