// Given a total due and an array representing the amount of change in your pocket, 
//determine whether or not
//  you are able to pay for the item. Change will always be represented in the following order: 
//  quarters, dimes, nickels, pennies.

// To illustrate: changeEnough([25, 20, 5, 0], 4.25) should yield true, since having 
// 25 quarters, 20 dimes, 5 nickels and 0 pennies gives you 6.25 + 2 + .25 + 0 = 8.50.
