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

Step-by-step explanation:

Let

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

Remember that

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

Solve for x

Divide by 1.3 both sides

answer: 590

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
