Final answer:
Trigg would be able to travel a total distance of 642.6 miles.
Step-by-step explanation:
To find the total distance the boys could travel, we need to determine the amount of gas Trigg can buy with $23.50. Trigg already has 5 gallons of gas in his tank, so the remaining amount he needs to buy is given by:
Gallons of gas = Amount spent on gas / Cost per gallon
Gallons of gas = $23.50 / $1.25 = 18.8 gallons
Thus, the total amount of gas Trigg has is 5 gallons + 18.8 gallons = 23.8 gallons.
To find the total distance the boys could travel, we multiply the gas mileage (27 miles per gallon) by the total amount of gas:
Total distance = Gas mileage * Total gallons of gas
Total distance = 27 miles/gallon * 23.8 gallons = 642.6 miles
