I Need Help can anyone figure out the answer to this problem a store sells cans of tomatoes price to show what size can of tomatoes has the lowest cost per ounce

Answer: 15 ounces
Step-by-step explanation:
We need to find the unit rate for each of the prices/ounces,
0.89/10 = 0.089
1.29/15 = 0.086
2.26/18 = 0.125...
3.39/32 = 0.1059375
The answer is:
B. 15 ounces
Because the unit rate(cost per ounce) is 0.086 cents per ounce which is less than:
A. 0.086
C. 0.126
D. 0.106
