Justin has a home-based business putting on children's parties. he charges $30 to design the party and then $10.00 per child. write a function rule that relates the total cost of the party to the number of children n.

The total cost of the party (C), can be expressed as;

C=10 n+30, where n is the number of children

Step-by-step explanation:

Step 1

We can use the expression below to calculate the total cost of the party as shown;

C=F+(V×n)

where;

C=total cost of the party

F=fixed cost to design party

V=cost per child

n=number of children at the party

In our case;

F=$30

V=$10

n=n

replacing;

C=30+(10×n)

C=30+10 n

The total cost of the party (C), can be expressed as;

C=10 n+30, where n is the number of children

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
