Let’s solve each problem one by one, step by step.
---
Problem 1:
Total parking spots = 1,327
First level has 162 spots.
So, remaining spots for the other 5 levels = 1,327 - 162 =
1,165
These 1,165 spots are split equally among 5 levels.
So, per level (including top level) = 1,165 ÷ 5 =
233
✔ So, the top level has
233 parking spots.

Problem 2:
Each level has 12 reserved spots for drivers with disabilities.
There are 6 levels total.
So, total reserved spots = 12 × 6 =
72
✔ Answer:
72

Problem 3:
We already know from Problem 2 that there are 72 spots reserved for drivers with disabilities.
Also given: 285 spots are for monthly rentals.
Total spots in lot = 1,327
So, hourly parking spots = Total - disability spots - monthly rental spots
= 1,327 - 72 - 285
Let’s calculate:
1,327 - 72 = 1,255
1,255 - 285 =
970
✔ Answer:
970

Problem 4:
Daily rate = $30
Jack parks 5 days a week → weekly cost = 30 × 5 = $150
He does this for 4 weeks a month → monthly cost = 150 × 4 = $600
In a year (12 months) → yearly cost = 600 × 12 =
$7,200
✔ Answer:
$7,200

Problem 5:
Start: 816 cars parked
At lunch: 91 leave → 816 - 91 = 725 cars left
After lunch: 135 come back → 725 + 135 =
860 cars
Wait — but the question asks: “How many parking spots were left on Monday afternoon?”
That means: how many empty spots? Not how many cars are there.
Total spots = 1,327
Cars present in afternoon = 860
So, empty spots = 1,327 - 860 =
467
✔ Answer:
467

Problem 6:
Hourly rate = $x
Each car parks 7 hours/day → revenue per car per day = 7x
All 1,327 spots taken → total revenue = 1,327 × 7x = 9,289x
Given: total revenue = $27,867
So equation:
9,289x = 27,867
Now solve for x:
x = 27,867 ÷ 9,289
Let’s divide:
9,289 × 3 = 27,867 → exactly!
So x =
3
✔ Equation: 9289x = 27867
✔ Solution: x = 3

Final Answer:
1. 233
2. 72
3. 970
4. $7,200
5. 467
6. Equation: 9289x = 27867; x = 3
