If brandon rents a truck for 30 dollars for four hours and 10 dollars for each additional hour he only has 60 dollars what is the maximum amount of hours he can rent the truck for explain in step form

After Brandon rent it for the first 4 hour, it cost 10$ per hour. 60$ (his money) subtracted by 30$ (he spent on first 4 hour) is 30$. This mean he only have 30$ to spent on remain hours. 30$÷10$ is 3, showing that he can rent it for 3 additional hours. 4 hours (from the 30$ for first 4 hour) plus 3 hours is 7 hours. The answer is 7 hours.
