Question

1. Which size jar of jelly shown in the table has the lowest unit price? 10 - 1.6616 - 3.1932 - 5.79

Answer 1

You have to devide size by cost, of all your options

for the first case..

$value=\frac{1.69\text{ \ }}{10\text{ oz}}=\text{ 0.169 }$

For the second

$\text{value = }\frac{3.19\text{ \ }}{16\text{ oz}}\text{ = 0.199}$

and thrird

$\text{value = }\frac{5.79\text{ \ }}{32\text{ oz}}=0.181$

you can solve the division for all of them and get te value for 1 oz of jelly, and we choose the lower one..

the answer is the first one case,
