After a 90% reduction, you purchase a new soft drink machine on sale for $80. what was the original price of the soft drink machine?

it means i only paid for %10 out if the 100%.

so therefore, the original price is;

100/10×80=$800

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

because that’s us why
