Answer:
(5,225)
Step-by-step explanation:
The break even point is when the cost equals the revenue.
C=R
15x+150=45x
150=30x
x=5
Plug this back into the original equations to get the y value.
15*5+150=225
or 45*5=225
First you multiply 44 and .20 (you cant multiply a percentage so you move the decimal left 2 times)
Second, subtract what you got from 44
That's it!

Answer:
(2, 5)
Step-by-step explanation:
Let the number of fancy throw pillows be x.
Let the number of plain throw pillows be y.
Hope spent a total of $131 on 7 throw pillows.
Fancy throw pillows cost $28 and plain throw pillows cost $15.
These imply two things:
x + y = 7 _______ (1)
28x + 15y = 131 ___(2)
We have a linear system of equations.
From (1):
x = 7 - y
Substitute the value of f into (2):
28(7 - y) + 15y = 131
196 - 28y + 15y = 131
196 - 13y = 131
=> 13y = 196 - 131
13y = 65
y = 65 / 13
y = 5
This means that:
x = 7 - 5 = 2
Hope bought 2 fancy throw pillows and 5 plain throw pillows
