A math club is having a bake sale as a fundraiser to raise money for an upcoming trip. They sell $54$ cookies at three for $\$1$, and $20$ cupcakes at $\$2$ each, and $35$ brownies at $\$1$ each. If it cost the math club $\$15$ to bake these items, what was their profit?

Gross profit= $114

Step-by-step explanation:

Giving the following information:

Total cost= $15

First, we need to calculate the total sales:

Total sales= 54*$1 + 20*$2 + 35*$1

Total sales= $129

Finally, the gross profit:

Gross profit= sales - total cost

Gross profit= 129 - 15

Gross profit= $114

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
