First, find how much he paid by tire.
To do so, divide what he paid by how many tires he bought like this :
240$ / 12 = 20$ per tire
Then, calculate how much he sells each tire.
To do so, start by calculating how much he paid for 3 tires:
20$ x 3 = 60$
This is the price he sells 2 tires for, therefore :
60$ / 2 = 30$
he sells his tires 30$ each.
Finally, you have to calculate the profit he made by selling 12.
We already know how much it cost, so you need to find how much money he gets selling them :
12 tires x 30$ = 360$
To find the profit, take off the amount he paid from the amount he made :
360$ - 240$ = 120$
There you go!
The answer is the letter c. 3
Answer:

Step-by-step explanation:
Set up an equation and solve for r using the formula for slope:

A clock is 12 hours.
11 hours and 38 minutes is 22 minutes short of being a full 12 hours.
In 12 hours the time would be 5:35 again, so now subtract 22 minutes from the time:
5:35 - 22 minutes = 5:13
In 11 hours and 38 minutes, the time will be 5:13
