Murillo · Answer 1

First we have to setup the system of equations for the given case.

Small bottles=s

Large bottles=l

Equations are:

l=2s Equation 1

2.5s+3l=357 Equation 2

Substitute value of l in equation 2.

2.5s+3 (2s) = 357

2.5s+6s=357

8.5s=357

s=42

Now substitute value of s in equation 1.

l=2 (42)

l=84

So they sold 42 small bottles and 84 large bottles of water.

Total bottles = 126
