Step-by-step explanation:
Here, we want to differentiate between inverse and direct proportion
Let x and y be two quantities
If they are directly proportional;
x/y = k
x = ky
where k is proportionality constant
If inversely;
xy = k
In verbal terms;
For direct proportionality, when one value increase, the other too does so and vice versa
For inverse, when one value inverse, the other decrease
(22a) 1500 x 1.6 x 2
(22b) DEV 1500 x 1.8=2700 1500 x 1.3=1950 2700+1950=4650 1500 x 1.6 x 2= 4800 4650(Emma) < 4800(Dev)
I strongly suggest to check my work. Good Luck and hoped I helped at least a little (I am very tired and it was almost midnight when I did this sorry for any errors).
