Answer:
One blueberry pie = $7
One pumpkin pie = $16
Step-by-step explanation:
Since there are two variables in this problem - the cost of blueberry pie and the cost of pumpkin pie, we can set up a system of equations to solve. Since Brandy sold 6 blueberry pies and 4 pumpkin pies for $106, our first equation is: 6b + 4p = 106.
Molly sold 6 blueberry and 3 pumpkin for $90, so the second equation is: 6b + 3p = $90.
We can use elimination to add the two equations together and eliminate one variable while we solve for the other:
6b + 4p = 106
6b + 3p = 90
In order to eliminate a variable, you can multiply the first equation by -1:
-1(6b + 4p = 106) = -6b - 4p = -106
Add<u> 6b + 3p = 90</u>
-p = -16, so p = 16
Now, solve for b: 6b + 3(16) = 106 or 6b + 48 = 90
Subtract 48 from both sides: 6b + 48 - 48 = 90-48
Divide by 6: 6b/6 = 42/6
Solve for b: b = 7
Answer:
???
Step-by-step explanation:
Step-by-step explanation:
Let p and h represent pay and hours worked respectively,
p = kh
k = p/h = 148.5/18 = 8.25
p= 8.25h
90.75 = 8.25h
h = 11 hours.
Hope it helps! :)
<h3>Explain why it is helpful to know the basic function shapes and discuss some ways to remember them. </h3>
- Knowing the basic function shapes and discuss some ways to remember them is helpful because this is useful tools in the creation of mathematical models because we constantly make theories about the relationships between variables in nature and society. Functions in school mathematics are typically defined by an algebraic expression and have numerical inputs and outputs.
