Answer:
9.5 ft^2
Step-by-step explanation:
It’s just 4.75 * 2
1.25 hours for each lawn. 1.25 x 7 = 8.75.
Here is the set up:
(1/4)/2 = (9/4)/y
Solve for y.
It would be zero because you can’t raise 0 to any positive power.
<u>Answer:</u>
$50 and $115
<u>Step-by-step explanation:</u>
We know that,
the sum of the two rates = $165 per hour
Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.
Then combining their charges together to get:

Solving for x to get:



So the rate charged per hour by one mechanic is $50 and for the other mechanic =
$115.
