Susan wants to make pumpkin bread and coffee cakes for the school bake sale. She has 15 eggs and 16 cups of flour in her pantry. Her pumpkin bread recipe uses 2 eggs and 3 cups of flour. Her coffee cake recipe uses 3 eggs and 4 cups of flour. She plans to sell pumpkin bread loaves for $5 each and coffee cake loaves for $4 each. Susan wants to maximize the money raised at the bake sale. Let x represent the number of loaves of pumpkin bread and y represent the number of loaves of coffee cake Susan bakes. What is the objective function for the problem? A. P = 15x + 16yB. P = 5x + 7y
C. P = 5x + 4y
D. P = 4x + 5y

Answers

Answer:

Option C is correct that is  P=5x+4y

Step-by-step explanation:

We have given  She has 15 eggs and 16 cups of flour in her pantry. Her pumpkin bread recipe uses 2 eggs and 3 cups of flour. Her coffee cake recipe uses 3 eggs and 4 cups of flour

Let x represents number of loaves of pumpkin bread

And y represents the number of loaves of coffee cake Susan bakes

Since, She plans to sell pumpkin bread loaves for $5 each and coffee cake loaves for $4 each.

Hence, P=5x+4y

Therefore, option C is correct.
The answer is C because in the problem, it states that Susan is selling pumpkin bread for 5 dollars, in which would be 5x. It also stated that she is selling coffee cake for 4 dollars each, in which would be 4x. When you add 5x and 4x, you will get the objective function.

Can you solve for t in -100=12t-4?

Answers

-100=12t-4\n\n12t-4=-100\ \ \ \ |both\ sides\ +4\n\n12t=-96\ \ \ \ |both\ sides\ :12\n\n\underline{\underline{t=-8}}
The answer to your question is:  Yes, I can.

=================================

Although you didn't ask for the solution, I'm here now, so
I might as well follow through and make good my boast.

-100 = 12t - 4

Add 4 to each side of the equation:

-96 = 12t

Divide each side by 12 :

-8 = t

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold? a. 6
b. 9
c. 12
d. 15

Answers

we have to solve simultaneous equations.
                                                                     
x = 10 oz. boxes
                                                                     
y = 16 oz. boxes
                                                                               
simultaneous equations
                                                                     
x + y = 24 ---1)
                                                                     
3.50x + 5.00y = 97.50 ----2)
                                                                   
to solve for x we need to eliminate y, therefore we have to multiply 1st equation by 5
                                                                   
5x + 5y = 120 --3)
                                                                   
subtract 3) - 2)
                                                                   
5x - 3.50x = 120 - 97.50
                                                                   
1.50x = 22.5 x = 15
                                                                     
number of 10 oz. boxes are 15. answer is d.15
