0.80

Step-by-step explanation:

if she wrote 1.00, that would basically mean 1/1. that is 100%, so that doesn't work. if she wrote 0.8/1, then it means 80% of 1. basically just 80%. that's the percentage of what you got on your test, so that's the answer.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
