An electronic store sells 70 digital cameras per month at a price of $320 each. for each $20 decrease in price, about 5 more cameras are sold. use the verbal model and quadratic function to determine how much the store should charge per camera to maximize monthly revenues

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
