Answer:
19
Step-by-step explanation:
To write an equation for the first situation, you need to determine which factors can be changed. Â The bus will not change since you can have multiple people in one. Â The ticket to the museum is per person. Â This will change depending on how many people there are.
450 + 15.75x
For the second equation, you need to find how many people can go for it the cost to be equal to $40 per person. Â Set the equation equal to $40 per person and solve.
450 + 15.75x = 40x
450 = 24.25x
x = 18.56
Round up to 19 since you can't 0.56 of a person.
