Answer:
Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)
Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

Percent change = [(Value after - Value before) / Value before]*100
=%
=%
=%
=% ( Rounded to nearest tenth)
Percentage increase is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
Answer:
x=1
Step-by-step explanation:
3x-y=3
y=3-3x
9x-3y=9
9x-3(3-3x)=9
9x - 9 + 9x=9
9x + 9x=9 + 9
18x=18
x=18÷18
x=1
