To get the answer, you need to think of it like a see-saw.
Both sides must equal the same relative to 33.5. For example, 32 is 1.5 away from 33.5 so you could say you have 1.5*4 (because theres 4 tubes with 32 sweets). If you were to do this for the whole table, it would look something like this:
![(1.5*4)+(0.5*x)=(0.5*9)+(1.5*1)+(2.5*1)](https://tex.z-dn.net/?f=%281.5%2A4%29%2B%280.5%2Ax%29%3D%280.5%2A9%29%2B%281.5%2A1%29%2B%282.5%2A1%29)
This simplifies to:
![6+0.5x=8.5](https://tex.z-dn.net/?f=6%2B0.5x%3D8.5)
![0.5x=2.5](https://tex.z-dn.net/?f=0.5x%3D2.5)
![x= \frac{2.5}{0.5}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B2.5%7D%7B0.5%7D)
![x=5](https://tex.z-dn.net/?f=x%3D5)
This method can sometimes be inefficient depending on how many values but is probably the simplest way to solve this problem.
hope this helps :)
(sorry the other way is kinda hard to explain possibly ask your teacher tomorrow)
I don't think you need answer for that you already did it.
Answer:
4
Step-by-step explanation:
Amount spent on coffee = 70 - 39.56 = 30.44
One pound costs 7.61, how many will cost 30.44
7.61 : 1 = 30.44 : X
7.61 = 30.44/X
X = 30.44/7.61
X = 4

Answer:
26in^2
Step-by-step explanation:
5 time 4 is 20in^2. plus 2 times 3 is 6in^2.
add 20 and 6 then you get 26in^2.
