Literally Louise didn't pay anything, the bank just deducted the negative balance to her paycheck. to answer how much the she paid, the answer is $33.72, this is the negative amount balance on her bank.
You would first make an equation to show their individual price per hour multiplied by hours worked then added together to equal total cost. let X be mechanic 1 and Y be mechanic 2
10x + 5y = 1225
the second equation will use their price per hour added together to equal combined cost per hour
x + y = 180
you would solve by substitution. to do so, isolate either x or y in the second equation. for convenience, I will isolate x
x = 180 - y
plug in (180 - y) for x in the first equation
10(180-y) + 5y = 1225
1800 - 10y + 5y = 1225
-5y = -578
y = 115.6
this means that the second mechanic charges $115.60 per hour
to find the price per hour for the first mechanic, plug in (115.6) for y in the second equation
x + 115.6 = 180
x = 64.4
the first mechanic charges $64.40 an hour

Answer:
The gear ratio is 2.5 :1.
Step-by-step explanation:
A gear ratio is the ratio of the teeth on the front sprocket and the teeth on the rear sprocket.
Given is that the bike has 45 front teeth and 18 rear sprocket teeth.
So, gear ratio will be 
Hence, the ratio is 2.5 :1.
