200 miles will allow to stay within the budget
Step-by-step explanation:
∵ The daily budget is 82
∵ The cost per mile is 21/100 = $0.21
∵ The number of miles is x
∴ The equation of the budget is:
∴ 82 = 40 + 0.21 x
∴ 0.21 x = 82 - 40
∴ 0.21 x = 42
∴ x = 42/0.21 =200
∴ The number of miles = 200 to stay in the daily budget
