Question is Incomplete, Complete Question is given below;

Cindy spent $15.25 on ingredients for a blueberry pie and $12.84 on ingredients for a cherry pie. Each slice of pie sells for $3.50. Part A Which expression represents Cindy's profit if she sells b slices of blueberry pie and c slices of cherry pie?

A. 28.09(b + c) – 3.50

B. 3.5(b + c) – 28.09

C. 3.5b – 28.09c

D. 28.09b + 3.25c

Part B Cindy sells 24 slices of blueberry pie and 15 slices of cherry pie. What was her profit?

A. $28.09

B. $55.91

C. $108.41

D. $136.50

For Part A answer is B. 3.5(b + c) – 28.09

For Part B answer is C. $108.41

Step-by-step explanation:

Given:

Money Spent on Blueberry pie = $15.25

Money Spent on cherry pie =  $12.84

Solving for Part A.

We will first find the Total Money Spent on Both.

Total Money Spent on Both is equal to sum of Money Spent on Blueberry pie and Money Spent on cherry pie.

Total Money Spent = $15.25 + $12.84 =$28.09

Now Each slice are sold = $3.50

Let number of slices of blueberry pie sold be b.

and Number of slices of cheery pie sold be c.

Now Money earned by selling slices of pie is equal to price of each slice is sold multiplied by sum of number of slices of Blueberry pie and Number of slices of cherry pie.

Money earned =

Now We need to find the Profit after selling the slices pie.

Total profit can be calculated by Subtracting total money spent on both with Money earned by selling both.

Hence Total Profit =  

Hence The Expression representing Cindy' profit is

Now Solving for Part B.

Given:

b = 24

c =  15

Total Profit =  

Substituting the Values we get;

Total Profit =

Hence Total Profit Cindy made is $108.41.

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
