Explanation
To answer the question, we will make have to find the unit rate to get the best price
For option 1
26 treats per $4
[tex]unit\text{ rate=}\frac{\text{ \$}4}{26}=\text{ \$}0.1535[/tex]
For option 2
48 treats for 8 dollars
[tex]unit\text{ rate =}\frac{\text{ \$}8}{48}=\text{ \$0.1667}[/tex]
Option 3
57 treats for 9 dollars
[tex]unit\text{ rate=}\frac{\text{ \$9}}{57}=\text{ \$0.1579}[/tex]
Option 4
[tex]unit\text{ rate=}\frac{\text{ \$16}}{100}=\text{ \$0.16}[/tex]
So the best is the one with the lowest unit rate
This is $0.1535
Which is
