A classroom fish tank contains x goldfish. The tank contains 4 times as many guppies as goldfish. Enter an equation that represents the total number of guppies, y, in the fish tank.
The phrase 4 times as many means we multiply the goldfish (x) by 4 to get the number of guppies (y):
y = 4x
The phrase 4 times as many means we multiply the goldfish (x) by 4 to get the number of guppies (y):
y = 4x
