12-pack for 1.69 is a better buy
<em><u>Solution:</u></em>
Given that, Mike bought a 12-pack for 1.69 and Mary bought a 24-pack for 3.18
We have to find which is the better buy
First we have to find the unit rate
Unit rate is cost of 1 pack
<em><u>Mike bought a 12-pack for 1.69</u></em>
Therefore,
Cost of 12 pack = 1.69
Cost of 1 pack is found by dividing 1.69 by 12
Thus unit rate of Mike is 0.14083 dollar per pack
<em><u>Mary bought a 24-pack for 3.18</u></em>
Cost of 24 pack = 3.18
Cost of 1 pack is found by dividing 3.18 by 24
Thus unit rate of Mary is 0.1325 dollars
<em><u>On comparing both the unit rate</u></em>
Thus unit rate of Mike is larger
Thus, 12-pack for 1.69 is a better buy
This distance can be expressed as 3.84× m.
What is distance with example?
- Distance is a scalar quantity.
- The distance of an object can be defined as the complete path travelled by an object.
Given the distance between the earth and the moon is 384000km
Representing in exponential notation,
=384000×1000m [∵1km=1000m]
=384× m
=3.84× m
