The profit of a company receives is given by the expression 0.15(855p - 315) where p is the number of problems sold. Rewrite thi
Goryan [66]

The profit for 25 products sold and 150 products sold are 3159 and 19190.25 respectively.

<u><em>Explanation</em></u>

The profit of a company receives is given by the expression:  0.15(855p - 315)

Simplifying this expression using distributive property, we will get .....

0.15(855p - 315) \\ \\ = (0.15*855p)-(0.15*315)\\ \\ =128.25p-47.25

So, the simplified expression for profit will be:  128.25p-47.25

As p represents the number of products sold, so for finding the profit for 25 products sold and 150 products sold, <u>we need plug p=25 and p=150 separately into the above expression</u>.  

For p=25,  Profit =128.25(25)-47.25 = 3206.25-47.25= 3159

For p=150, Profit =128.25(150)-47.25 = 19237.50-47.25= 19190.25

A chef uses 3 3/4 pounds of semolina flour and 1 5/8 pound whole wheat flour for each batch of pasta she makes.one week she uses
Maurinko [17]
It is to be noted that for this item, we more concern of the pounds of flour. The number of batches is calculated by dividing the total mass of flour used by the amount per batch. That is,
                                              n = 86 lbs / (1 + 5/8 lbs/batch)
                                              n = 52.92 batch
Thus, the chef makes approximately 53 batches of pasta.
