Answer: 745
Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:
25% = 0,25
increase is 1+0.25
M1 = 80.(1+0.25)¹ = 80.1.25 = 100
M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)

The miles that can be travelled in the car on $30 gasoline is 240 miles (option A).
<h3>How many miles can the car travel?</h3>
The first step is to determine the total gallons in the car. The total gallons in the car can be determined by dividing the total value of the gasoline the car by the cost per gallon. Division is the process of determining the quotient of two or more numbers.
Total gallons = total value of gasoline in the car / cost per gallon
$30 / $2.50 = 12 gallons
The next step is to determine the total miles that the car can travel using the gallons available. To determine the total miles, multiply the total gallons by the number of miles that that one gallon can cover.
Total miles = miles one gallon can cover x total gallons in the car
12 x 20 = 240 miles
