A group of friends wants to go to the amusement park. They have no more than $320 to spend on parking and admission. Parking is $9.25, and tickets cost $28.25 per person, including tax. Write and solve an inequality which can be used to determine p, the number of people who can go to the amusement park.
___________________________________________
Please, give me some minutes to take over your question
________________________
They have no more than $320 to spend on parking and admission
320 ≥ 9.25 + 28.25*p
9.25 + 28.25*p ≤ 320
320- 9.25 ≥ 28.25*p
310.75/28.25 ≥ p
p ≤ 11
__________________________
Answer
The number of people who can go to the amusement park can be a maximum of 11 people (less than or equal to 11).
Multiplication would be the inverse operation of division. so it would be, 3 x 34 = 102
