Answer:
984
Step-by-step explanation:
DVDs comprises 31.3% of total. And we also know that there are 308 DVD. Thus, we can say:
308 is 31.3% of total
We can let total be x, thus we can write an equation as:
308 = 0.313x
Solving for x:

We can round and say there are 984 total movies
Answer:
32
Step-by-step explanation:
I will note Huilan as H and i will note Thomas as T
T = H + 6
T + H = 58
H+H+6 =58
2H = 58-6
2H = 52
H = 52/2
H = 26
T = H+6
T = 26+6
T = 32
