b. On another trip Johnny is planning, he will drive 540 miles with the same car. If gas costs $3.50 per gallon, how much should he budget for gas for this trip? (Section 18.3) (2 points) c. Cherie is planning a road trip of 1,500 miles. Her car gets 25 miles per gallon, and gas costs $3.35 per gallon. How much should she budget for gas for the trip? (Section 18.3) (2 points) 4. Tina budgeted $1,800 for her trip to Peru. Her roundtrip airfare is $800 and she calculated her daily cost of hotel/food/transportation to be approximately $100 per day. How many nights can Tina stay in Peru? (Section 18.4) (2 points)
missing information
i got the first question . 3. On a recent road trip, Johnny was able to drive 360 miles on 12 gallons of gas.
a. What is the average gas mileage for Johnny’s car? (Section 18.3) (2 points) 1/30 gallon per mile
12/360=1/30
b. To calculate how much Johnny should budget for gas for his trip, we need to determine the number of gallons of gas he will need and then multiply it by the cost per gallon.
First, we need to find out how many gallons of gas Johnny's car will consume for a 180-mile trip. Let's assume his car has a fuel efficiency of 25 miles per gallon. Therefore, we can divide the total distance he will drive (540 miles) by the fuel efficiency (25 miles per gallon) to find the number of gallons he will need:
540 miles / 25 miles per gallon = 21.6 gallons
Since Johnny cannot purchase a fraction of a gallon, we need to round up to the nearest whole number. So, Johnny will need approximately 22 gallons of gas for the trip.
To find the total cost of gas for the trip, we multiply the number of gallons by the cost per gallon, which is $3.50:
22 gallons * $3.50 per gallon = $77
Therefore, Johnny should budget $77 for gas for this trip.
c. To calculate how much Cherie should budget for gas for her road trip, we need to determine the number of gallons of gas she will need and then multiply it by the cost per gallon.
First, we can determine the number of gallons of gas Cherie's car will consume for the 1,500-mile trip. Her car gets 25 miles per gallon, so we can divide the total distance (1,500 miles) by the fuel efficiency (25 miles per gallon) to find the number of gallons she will need:
1,500 miles / 25 miles per gallon = 60 gallons.
Therefore, Cherie will need approximately 60 gallons of gas for her road trip.
To find the total cost of gas for the trip, we multiply the number of gallons by the cost per gallon, which is $3.35:
60 gallons * $3.35 per gallon = $201.
Thus, Cherie should budget $201 for gas for her trip.
4. To calculate the number of nights Tina can stay in Peru within her budget, we need to subtract the cost of her roundtrip airfare and the estimated cost of her expenses from her total budget.
First, we subtract the cost of her roundtrip airfare ($800) from her total budget ($1,800):
$1,800 - $800 = $1,000
Next, we need to divide the remaining budget by the estimated daily cost of hotel/food/transportation ($100) to find the maximum number of nights she can stay:
$1,000 / $100 per night = 10 nights
Therefore, Tina can stay a maximum of 10 nights in Peru within her budget.
