Please answer this correctly I have to finish the sums by today as soon as possible

The second model, and the amount of exhibits the aquarium has is 40.

Step-by-step explanation:

The model is an easy one to figure out, 36 is 90% of the exhibits, not 100%.

Now for the second part : 36 out of what is 90%?  (what is the 100%?)

36 out of X is 90%

Equation: Y/X = P%

Solving our equation for X

X = Y/P%

X = 36/90%

Converting percent to decimal:

p = 90%/100 = 0.9

X = 36/0.9

X = 40
