Answer:

[tex]13,846\ cones[/tex]

Step-by-step explanation:

Let

x -----> the number of ice cream cones sold 5 years ago

Remember that

[tex]100\%+30\%=130\%=130/100=1.3[/tex]

we know that

Sales 5 years ago, multiplied by the 30% increase should equal 18,000 ice cream cones.

so

The linear equation that represent this problem is

[tex]1.30x=18,000[/tex]

Solve for x

Divide by 1.3 both sides

[tex]x=13,846\ cones[/tex]
