Answer:
He earned $300 all summer
Step-by-step explanation:
We are asked to write an equation and also determine the amount Ali earned all summer if he collected $75 mowing fee from a neighbor and this constitutes 1/4 of the few he had collected all summer.
Now, let the total amount of money he had all summer be $y
He collected a fourth equivalent to $75, this means 1/4 * y = 75 or y/4 = $75
Now we calculate y as y = $75 * 4 = $300
