Answer:
2
Step-by-step explanation:
f(-1)=2(-1)+2+1
f(-1)=-2+2+1
f(-1)=1
f(0)=2(0)+2+1
f(0)=0+2+1
f(0)=3
Use slope formula for the average rate of change.
(y2-y1)/(x2-x1)
(3-1)/(0+1)
(2)/(1)
2
Hope this helps!
If not, I am sorry.
Answer:The first option has a higher cost per liter and the required cost is $1.40 per liter.
Step-by-step explanation:
Step-by-step explanation: Given that a 2 liter bottle of juice cost $2.80. A box containing six 12 liter bottle sells for $3.90.
We are to select the option that has a higher cost per liter.
We will be using the UNITARY method to solve the given problem.
Option (1) :
The cost of 2 liter bottle of juice = $2.80.
So, the cost of 1 liter bottle of juice will be
Option (2) :
The cost of six 12 liters bottle of juice = $3.90.
So, the cost of 1 liter bottle of juice will be
Since 0.05>1.40, so the option of 2 liter bottle costing $2.80 has a higher cost per liter.
And, the required cost is $1.40 per liter.
