3 pack of gum- Unit Rate
The package says there is 14 pieces per pack and there is 3 packs so to find how many total pieces there are we have to multiply. So, 14 x 3= 42 Total Pieces.
2. Now the next step is to find the price. Well the price tag says it is $2.00
3. To find the unit rate we need to divide 2.00 divided by 42= 0.048
4. Our unit rate is 0.048 for each stick of gum.
Varierty pack of Gum- Unit Rate
1. Lets find the Unit Rate for the Variety Pack
The package says there are 12 packages and 14 sticks of gum per pack. To find how many total pieces there are we need to multiply. So, 12 x 14= 168 Total Pieces.
2. Now the next step is to find the price. Well the price tag says $8.99.
3. To find the unit rate we need to divide 8.99 divided by 168= 0.053
4. So our unit rate is 0.053 for each stick of gum.
Best Buy?
Lets break this down. So the unit rate of the 3 Pack is 0.048 per piece and the Variety pack is 0.053 per piece. The difference is 0.005 meaning the Variety pack is only 0.005 more.
Or you can say 3 Pack- $2.00 = 42 TP, $4.00 = 84 TP, $6.00 = 126 TP, $8.00 = 168 TP so you can buy 4 of the 3 pack and it will equal the same amount of the variety pack but a dollar less. The unit rate is important because you could be spending a dollar more when you can just grab 4 of the 3 Pack packages. So the 3 pack wins!!

Unit Rate- 12 Pack
Since we know that there are 12 Total Bottles in the package and the price is $2.63 we can go ahead and divide the two. So, 2.63 divided by 12= 0.22 TB
2. So the the Unit Rate is 0.22 Per Bottle
Unit Rate- 24 Pack
Since we know there are 24 Total Bottles in the package and the price is $3.98 we can go ahead and divide the two. So, 3.98 divided by 24= 0.17
2. So the Unit rate is 0.17 Per Bottle
