The total earnings are calculated by multiplying the hourly rate by the number of hours worked per day and then by the number of days worked.
Daily earnings: $15 × 8 = $120
Total earnings: $120 × 5 = $600
First, calculate the total cost of the items Lisa bought:
3 books: 3 × $15 = $45
Notebook: $10
Total cost: $45 + $10 = $55
Next, subtract the total cost from the amount Lisa paid:
$100 - $55 = $45
The total cost is calculated as the daily rental fee plus the cost per mile driven.
Daily fee: $40
Mileage cost: 100 miles × $0.25 = $25
Total cost: $40 + $25 = $75
Multiply the speed of the train by the time it travels to calculate the distance.

Distance = Speed × Time = 60 × 3.5 = 210 miles
Subtract the points scored in the first half from the total points to find the second half's score.
