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.
<em>1452 feet</em>
- Step-by-step explanation:
<em>1 hour = 60min×60sec = 3600 sec</em>
<em>1 miles = 5280 feet</em>
<em>22 miles = 22×5280ft = 116160 ft</em>
<em />
<em>3600sec ................. 116160 ft</em>
<em>45sec ................................ x ft</em>
<em>x = 45×116160/3600</em>
<em>= 5227200/3600</em>
<em>= 1452 feet</em>
1/4= 0.25
2/4= 1/2 = 0.5
0.25 x 0.5 = 0.125
0.125 = 1/8
