wel

Answer: Total products = 108

Step-by-step explanation: Ratio of solid to liquid products is 3:4 and there are 36 solids, so:

$\frac{3}{4} = \frac{Pl}{36}$

$Pl = \frac{36.3}{4}$

Pl = 27

Ratio of solid to gas is 4:5:

$\frac{4}{5}=\frac{36}{Pg}$

$Pg=\frac{36.5}{4}$

Pg = 45

Total products is the sum of all products:

P = Ps + Pl + Pg

P = 36 + 27 + 45

P = 108

There are a total of 108 products.
