Matt's birthday party costs $3, plus an additional $1 for each guest he invites. Write an equation that shows the relationship between the guests x and the cost y

Write your answer as an equation with y first, followed by an equals sign.

y= 1x+3

Step-by-step explanation:

The ground payment to Matt's party $3.

If you end up bringing additional people, you will need to bring an extra dollar for each person.

Example 1: If you intend to bring 5 extra people (six including you) you will use the equation y=1x+3, so, you will do:

1x5=5

5+3=8

8 will be your final answer.

Example 2: If you intend to bring 10 extra people (eleven including you) you will use the equation y=1x+3, so, you will do:

1x10=10

10+3=13

13 will be your final answer.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
