There were 36 ounces of food left after 12 days.
After 12 days, the ounces of food left as shown by the graph is halfway between 40 and 32.
The halfway point between 32 and 40 can be calculated as:
= Difference between 32 and 40 / 2
= (40 - 32) 2
= 8/ 2
= 4 ounces
Add the halfway mark to the lower ounces mark on the ground of 32 to find the ounces in the bag after 12 days:
= 32 + 4
= 36 ounces
There were therefore 36 ounces of food remaining 12 days after Andre bought it.
