Answer:
x=30
Step-by-step explanation:
6 x 5 = 30
30/5 = 6
6(7)^2+4(7)+8=y
6(49)+28+8=y
294+28+8=y
330=y
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!
Answer:
I know the answer
Step-by-step explanation:
x = random number then y = x + y then x = 68 So we can conclude
