Step-by-step explanation:

Bowling:

15+5x  where x is the number of people

Skating:

20+3x

We have 50 dollars so the amount must be less than or equal to 50

Bowling

15+5x≤50

Subtract 15 from each side

15-15+5x≤50-15

5x ≤35

Divide each side by 5

5x/5 ≤35/5

x ≤7

She can have 7 or less people

Skating

We have 50 dollars so the amount must be less than or equal to 50

20+3x  ≤50

Subtract 20 from each side

20-20+3x  ≤50-20

3x  ≤30

Divide each side by 3

3x/3 ≤30/3

x ≤10

She can have up to 10 people

She can invite more people skating

1) C = 15 + 5x

2) C = 20 + 3x

3) 7

4) 10

5) Skating rink

Step-by-step explanation:

C : cost

Fixed: 15

Additional: 5

For x people,

C = 15 + 5x

Budget is 50:

15 + 5x《50

3x《35

x《7

C : cost

Fixed: 20

Additional: 3

For x people,

C = 20 + 3x

Budget is 50

20 + 3x《50

3x《30

x《10

Since 10 > 7, she can invite more people at the skating rink
