Question

sales at a local ice cream shop went up 30% in 5 years. if 18,000 ice cream cones were sold in that current year, find the number of ice cream cones sold 5 years ago

Answer 1

Answer:

$13,846\ cones$

Step-by-step explanation:

Let

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

Remember that

$100\%+30\%=130\%=130/100=1.3$

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

$1.30x=18,000$

Solve for x

Divide by 1.3 both sides

$x=13,846\ cones$
