Let

be the number of strawberry cupcakes, and

the number of chocolate cupcakes.
From our problem we know that the total number of cupcakes is 180, so

. We also know that the number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes, so

, or solving for

:

.
Know we have our system of equations:

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>

; lets replace that value in our first equation to find the number of strawberry cupcakes:




<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>



As a bonus, we can conclude that the <span>math club have 126 chocolate cupcakes and 54 strawberry cupcakes. </span>
I got 50.24
since 2*3.14*8=50.24
but if you want it rounded to the nearest tenth I guess it would be 50.2
Hope this helps :)
10/4 actually equals 2.5, so I can go ahead and multiply 2.5 by 0.7.
