<em>The correct answer is $2030. Using the formula for simple interest I = prt where p is the money amount, r is the interest rate in decimal form and t is time in years, you have I = (1450)(.10)(4) which is $580. This interest should be added back to the $1450 to get $2030.</em>
he has 5 gallons in the tank already.... buys gas at 1.25 per gallon.....spends $ 22...so he buys 22 / 1.25 = 17.6 gallons so he has a total of (5 + 17.6) = 22.6 gallons....at 22 miles per gallon = 22.6 * 22 = 497.2 miles <==
