Answer:
A = 2
Step-by-step explanation:
If A = 4 when B = 88, we can divide both A and B by 2 to find their values.
88/2 = 44
4/2= 2
We can also check this by dividing 88 by 4 to figure out that A = 1 when B = 22
We can then multiply both the values of A and B to get a proportional relationship of A = 2, B = 44
