Andre’s coin jar contains 85 cents. There are no quarters or pennies in the jar, so the jar has all nickels, all dimes, or some of each.[br][br]Write an equation that relates the number of nickels, [i]n[/i], the number of dimes, [i]d[/i], and the amount of money, in cents, in the coin jar.
0.05[i]n[/i] + 0.10[i]d[/i] = 0.85[br] or[br]5[i]n[/i] + 10[i]d[/i] = 85
Graph your equation on the coordinate plane.
How many nickels are in the jar if there are no dimes?[br]
How many dimes are in the jar if there are no nickels?[br]
It’s not possible for the coin jar to have no nickels if the amount of money in it is 85 cents.
