Calculus problem: In this problem, p is in dollars and x is the number of units. Find the producer's surplus at market equilibrium for a product if its demand function is p = 121 − and its supply function is p = + 6x + 65. (Round your answer to the nearest cent.)

Solution: $ _

answer: the correct one is a

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
