# Thread: Area Between Two Curves, Again

1. ## Area Between Two Curves, Again

Can someone tell me where I messed up at? The answer is $7052.48 Find the producer's surplus if the supply function for computers is given by$\displaystyle S(q)=5q^{3/2}+q+61$and supply and demand are in equalibrium at$\displaystyle q=22$Here is my work.$\displaystyle S(22)= 5(22)^{3/2}+22+61\displaystyle =598.9457336\displaystyle \int_{0}^ {22} [598.9457336-(5q^{3/2}+q+61)]dq\displaystyle \int_{0}^{22} (537.9457336-5q^{3/2}-q)dq\displaystyle =537.9457336q-2q^{5/2}-q^2 \mid_{0}^{22}\displaystyle =11834.80614-4540.322456+484\displaystyle =7778.48$The reason I didn't round my calculations is because it said not to. As you can see my anwer is far from the right one of$7052.48....someone please help

2. When you integrate your last term, it should be (q^2)/2...you just forgot to divide the last term by 2 after you integrated it.

Hope this helps.
