Smith & Johnson produces a variety of men’s clothing. Their highest selling items are their fitted dress shirts. The profit earned from the sale of these shirts can be modeled by the expression -20x2+1,800x, where x is the price of one dress shirt. If p is the maximum profit earned from the sale of the dress shirts, write an equation that shows how the expression can be rewritten to model the price at which the shirts should be set in order to maximize profit.

Step-by-step explanation:

Step one:

given

Price

where P is the maximum profit

           x is the price of one shirt

Step two:

To rewrite the expression let us first divide through by 20

Factoring x out we have

Hence the rewritten expression equation for the price is

P=x(-x+90)

96°36'36".

Step-by-step explanation:

Given :  95.61.

To find : Change 95.61 to degrees,minutes and seconds.

Solution : We have given that 95.61

Here whole part represent the degree

So, 95 is degree.

For the minutes multiply the remaining decimal by 60.

0.61 * 60 = 36.60.

Use the whole number part (36) of the answer as minutes.

So, 36 is the minute .

For the seconds multiply the new remaining decimal( 0.60)  by 60.

0.60 * 60 = 36.00.

So, 36 is the second .

We can write 95.61 = 96°36'36".

Therefore, 96°36'36".
