Given:
c = cost
p = people
Spent $300
Formula: c=5p+215
Solving for how many people (p)
C=5P+215
(300)=5P+215 (Subtract 215 on both sides)
85=5P (Divide by 5 on both sides)
17=P
The answer is 17. 17 people can afford to host a birthday party.

Probability of getting at least 1 tail in 3 coin toss is 1−18=78
Answer:
(3, 140)
Step-by-step explanation:
If we have the equation
, we can substitute the value 3 as
to find the value of
.

So we know that the total cost is $140.
To represent this as an ordered pair, we need to take note that the independent variable (x) is the one that we change to get the result (y).
We changed
to get
, so
is the x and
is the y.
So it's represented as (3, 140).
Hope this helped!
