For A party 10 friends are byinh 100 cups 100 plates a punchbowl and 200 balloons if the friends share the cost equally how much should each friend contribute ? 100 Balloons:$7.80
100 plates:$4.75
100 cups:$5.45
100 napkins:$2.09
10 invitations: $1.60
plastic punchbowl$11.50

$2.58

Step-by-step explanation:

First, we should divide each number by 10 to get the amount per person we get...

10 cups

10 plates

20 balloons

Since the cost of cups, plates, and balloons is written as 100 of them, we just have to divide each of the by the amount we got after dividing by 10 and use that same amount and divide the money...

1. 10 cups is 1/10 of 100 cups so we divide $5.45 by 10 = .545

2. 10 plates is 1/10 of 100 plates so we divide $4.75 by 10 = .475

3. 20 balloons is 1/5 of 100 balloons so we divide $7.80 by 5 = 1.56

Now, we add them all up to get $2.58

Hope this Helps!!! :)

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

55 degrees because 55+55=110 degrees
