11 + 7 = 18
18+11= 29
Emily has 29 cakes
Answer:
Let x be the number of person and y be the total cost per person.
As per the statement:
A catering company charges a $300 set up fee and $10 per person for a lunch buffet.
"$10 per person" translated to 10x
then;
Total cost per person = 10x+300
It is also given that: total cost per person is $14.
⇒
Subtract 10x from both sides we have;
Divide both sides by 4 we have;
x = 75
Therefore, 75 number of people must attend the lunch so that the total cost per person is $14
CATERING TOTAL COST F(X) = 10X + 300
TOTAL REQUIRED 14X
10X + 300 = 14X
10X - 14X = -300
-4X = -300
4X = 300
X= 300/4
X=75 <------------------SOLUTION
Answer:
Step-by-step explanation:
Perimeter is the sum of all the sides
Answer:
P = 10y - 3
Step-by-step explanation:
Perimeter is dettermined by adding all the outside surfaces information together.
Watch:
First, set up:
(3y - 2) + (2y + 2) + (2y - 2) + (y) + (2y - 1)
Now add the common alikes.
(3y + 2y + 2y + y + 2y) = 10y
(-2 + 2 - 2 - 1) = -3
Now you have your perimeter.
P = 10y - 3
