Answer:
Step-by-step explanation:
let the Cookie Dough kit be x
and Baker’s Delight kit be y
cost of Cookie Dough kit= $7
cost of Baker’s Delight= $15
so
x+y=220------------1
7x+15y=2100------2
solve for x and y we have
multiply eqn 1 by 7 and subtract
7x+7y=1540---------3
- 7x+15y=2100-------2
0x-8y=-560
8y=560
divide both sides by 8 we have
y=560/8
y=70
put y=70 in eqn 1 we have
x+70=220
x=220-70
x=150
x=220-70
x=150
A. How many of each type of kit should your band purchase to raise the most money
Cookie Dough kit= 150
Baker’s Delight= 70
B. What is the most money that your band can raise?
Cookie Dough kit profit= selling price-cost price= 12-7= $5
Baker’s Delight profit= selling price-cost price= 25-15= $10
Amount made for Cookie Dough = 150*5=$750
Amount made for Baker’s Delight = 70*10=$700
total= 750+700= $1450

Step-by-step explanation:
I am thinking you mean 93 to represent William's scores of 91, 92, and "q3"on three quizzes in Queston 8a
Answer:Average (x)= 92
b.William needs 97 as his third score to get as average of 90
Step-by-step explanation:
a.
The Average ( x) of the scores can solved using the Formulae
Average ( x)= Sum of scores / Number of Scores
Average ( x) = (Score 1 + Score 2 + Score 3) /3
Average (x)= (91, 92, and 93 )/3=276/3 = 92
b) Average ( x) of the scores = Sum of scores/ Number of Scores
Now let Score be represented as S such that
Average (x) = (S 1 + S 2 + S3 )/ 3
90 = 85+ 88+ S/ 3
90 x 3= 85+ 88 + S
270=173+ S
S= 270- 173
S=97
William needs 97 as his third score to get as average of 90

Answer: The measure of non-reflex ∠DOB is 108° and the measure of reflex ∠DOB is 252°.
Explanation:
It is given that the reflex angle ∠DOB has measure of 3.5y while the measure of ∠AOD is y.
From the given figure we can say that angle AOC and COB are supplementary angles and their sum is 180 because they are lies on a straight line.
Therefore the value of y is 72.
Therefore the reflex and is 252 degree.
The measure of non-reflex ∠DOB is,
Therefore, the measure of non-reflex ∠DOB is 108° and the measure of reflex ∠DOB is 252°.
