Answer:
x = 9
Step-by-step explanation:
Substitute y=6 into 2x+3y=36
2x+3(6) =36
2x + 18 = 36
2x = 18
x = 9
I’m canadian so I’m not quite sure how the money itself works, but I can explain how to do them. The easiest way is to divide each option by the number of items per price. For example, in A option 1 is already 1 ticket/ £8 whereas in the second it’s 3 tickets/ £20. So divide both the 3 and the £20 so you get the price per individual ticket. In the end you get 1 ticket/ £6.66 meaning it is a better deal than option 1.
Store A would be least expensive
One way to do this problem is to take 26.65 and divide it by all of the values from $2.01 to $2.99. If one of these goes in evenly with no remainder then that is the cost of each notepad. The quotient (answer when you divide) is the number of pads. Since we can’t have half a pad, the number must go in evenly (leave no remainder).
While we can check each of these, I noticed that 26.65 ends in a 5 and so is divisible by 5 so I decided to check 2.05 as a possible price and it went in evenly. The quotient is 13.
thus, there were 13 notepads and the cost of each is $2.05
