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

Answer:
20x^50
Step-by-step explanation:
Answer:
This will be the sum of a geometric series where the first term is 4
The common ratio is -5
And we will have 6 terms.....so....the sum is
first term [ 1 - common ratio^number of terms ] / [ 1 - common ratio ] =
4 [1 - (-5)^6] / [ 1 - -5 ] =
4 [ 1 - 15625 ] / 6 =
(2/3) ( -15624 ) =
-10416
