Question

A shampoo comes in two sizes > a 12 fl. oz. bottle that sells for $3.32 and a 16 fl. oz. bottle for $3.80. calculate the unit price (price per fl. oz.). which one is the least expensive?

Answer 1

You would do:
3.32 divided by 12 = 0.276 reccuring
then do 3.80 divided by 16 = 0.2375 ( these are the prices each pr fl. )
Then compare the numbers together
0.276
0.2375
if you look the top one goes 2 then seven while the bottom one goes two then 3 so the bottom one is the lat expensive
hope this help
