The school is having a bake sale and the math club is bringing cupcakes. They have 180 total cupcakes, both chocolate and strawb
jeka57 [31]
Let s be the number of strawberry cupcakes, and c the number of chocolate cupcakes.
From our problem we know that the total number of cupcakes is  180, so c+s=180. We also know that the number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes, so c-18=2s, or solving for c: c=2s+18.
Know we have our system of equations:
\left \{ {{c+s=180} \atop {c=2s+18}} \right.
We can conclude that the correct answer is <span>B. c + s = 180 c = 2s + 18.

Lets solve our equations to find how many cupcakes of each they have:
from our second equation we know that </span>c=2s+18; lets replace that value in our first equation to find the number of strawberry cupcakes:
2s+18+2=180
3s=162
s= \frac{162}{3}
s=54
<span>Now that we know the number of strawberry cupcakes, lets replace that value in our second equation to find the number of chocolate cupcakes:
</span>c=2(54)+18
c=108+18
c=126
As a bonus, we can conclude that the <span>math club have 126 chocolate cupcakes and 54 strawberry cupcakes. </span>

Someone please help me with this algebra problem
nevsk [136]

Answer:

$110

Step-by-step explanation:

We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:

\frac{y_{2} -y_{1} }{x_{2}- x_{1} }

We can substitute the points given, (2, 480) and (5, 150) and simplify:

\frac{150-480}{5-2} =\frac{-330}{3} = -110

We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110
