Question 413233
Let x, x+2, x+4, x+6 be the number of pennies, dimes, nickels, and quarters respectively. Then,


x + 10(x+2) + 5(x+4) + 25(x+6) = 682 (you see how the algebraic equation is put together?)


x + (10x + 20) + (5x + 20) + (25x + 150) = 682


41x + 190 = 682


41x = 492 --> x = 12, so Michelle has 12 pennies, 14 dimes, 16 nickels, and 18 quarters.
