90
a.
The required equation is 23p + 19.50 = 180.50
Let p represent the number of people who can go to the amusement park.
Since the ticket costs $23 per person, the total amount paid for ticket is rate × number of person = $23 × p = 23p.
Since we pay $19.50 for parking, the total amount spent is T = 23p + 19.50
Since the total amount equals $180.50. T = 180.50
So, 23p + 19.50 = 180.50
The required equation is 23p + 19.50 = 180.50
b.
Solving 23p + 19.50 = 180.50, we have
23p = 180.50 - 19.50
23p = 161
p = 161/23
p = 7
So, the number of people who can go to the amusement park is 7.

Answer:
1380 in²
Step-by-step explanation:
The lateral surface is the sum of the areas of all the sides, or 'faces'.
The bases (the top and bottom) are <u>not </u>included.
This is a prism with triangles for bases (at each end). The sides are rectangles.
Add up the areas of the rectangles.
300 + 480 + 600 = 1380
The park charges 1.50 per ride.
1. Louisa bought 15 ride tickets at 1.50 each.
Equation: C = Entry Fee + 1.50t
t = 15.
c = 30.75
30.75 = Entry Fee + 1.50(15)
30.75 = Entry fee + 22.50
Entry fee = 30.75 - 22.50
Entry fee = $8.25
2. Entry fee was calculated as 8.25 from #1.
Tickets are 1.50 each.
He can spend 22.
22 = 8.25 + 1.50t
Subtract 8.25 from both sides:
13.75 = 1.50t
Divide both sides by 1.50:
t = 13.75 / 1.50
t = 9.2
He can buy 9 tickets.
