20. In Economics, the law of demand states that as the price of a commodity rises, the demand for that commodity goes down. A company determines that the monthly demand for a certain item that sells can be modeled by the function q(p) = -2p+34, where q represents the quantity sold in hundreds and p represents the selling price in dollars. It costs $7 to produce this items, How much more per month in profits can the company expect to earn by selling the item at $12 instead of $10? ( Profit = sales - costs)

Answer:

Samantha makes $ 7.98  per hour

Step-by-step explanation:

Amount  James makes per hour  =  $7 per hour

Let Amount priya make in one hour be  x , then

Priya makes 20% more than James

x =  Amount  James makes per hour  +  20 % of Amount  James makes per hour

x= 7 +  20% of 7

x = 7 +1.4

x= 8.4

Let amount made by samantha in one hour be y

then

y =Amount  priya makes per hour  -  5% of Amount  priya makes per hour

y = 8.4 -   5%  of 8.4

y= 8.4 - 0.42

y = 7.98
