Jimmy has a pocket full of nickels ans quarters. there are a total of 50 coins. when he added it all up he had $5.30. how many nickels did he have?

Nickel is x

quarter is y

x + y = 50 coins

5x + 25y = 530 cents

if x = 49

5 * 49 = 245 + 25 = 270

if x = 45

5 * 45 = 225 + (25 * 5) = 350

if x = 40

5 * 40 = 200 + (25 * 10) = 450

if x = 36

5 * 36 = 180 + (25 * 14) = 530

There will be 36 nickels and 14 quarters.
