The expanded form of 15,409 would be 15,000 + 400 + 9.
Your 15 would alone be 15,000. The 409 is turned into zeros.
For 409, take the 9 off of the end and keep it by itself, and then add a zero in replace for the 9, which makes 400.
The 9 should come in at the last part as it is the last number.
Add them all together and you should get <span>15,000 + 400 + 9.</span>
Yes it should be a negative nine not a positive nine
Have a nice day : )

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
