Answer:
First mechanic worked for 10 hours and second mechanic worked for 15 hours.
Step-by-step explanation:
Let first mechanic worked for X hours and second mechanic worked for Y hours .
Now, according to the question , they worked for a total of 25 hours .
Thus ,
X + Y = 25.
Y = 25 - X -(1)
Also, first mechanic is charging $ 95 per hour and second mechanic is charging $115 per hour .
Thus, total money charged by them will be 95X + 115Y .
Which is given to be $2675 in the question.
Thus 95X + 115Y = 2675. -(2)
Putting equation 1 in equation 2 we get ,
95X + 2875 - 115X = 2675
20X = 200
X = 10 hours.
Thus , Y = 25 - X = 15 hours.
Thus first mechanic worked for 10 hours and second mechanic worked for 15 hours.

The are ascending
Answer: -4h + 13
Step-by-step explanation:
(5h + 7) - ( 9h -6) is the same as (5h -9h) ( 7 + 6)
solve for each
5h - 9h = -4h
7+ 6 = 13
-4h + 13
This would follow the

format
where m would be the price per cup
and b would be the money you start off with
y = A
and x = j
so we get
A = 0.75j + 14
