In a college parking lot, the number of ordinary cars is larger than the number of sport utility vehicles by 42.9%. the difference between the number of cars and the number of suvs is 12. find the number of suvs in the lot.
let x = number of common cars y = number of suvs we can write the following system of equations x-y = 12 x = 1.429y Solving the system we have x-y = 12 1.429y-y = 12 and (1,429-1) = 12 y = (12) / (1,429-1) = 27.97202797 then, x = 1429 * (27.97202797) x = 39.97202797 answer The number of suvs in the parking lot is 28
