Janelle and three of her friends bought four smoothies for a total of $3. if she purchases smoothies on another day for herself and 9 of her friends, how much money will she spend?

answer: can and shows the work

step-by-step explanation:

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
