Answer: $0.10 per fluid ounce
Explanation:
Kayla bought two-pints for $3.20.
First convert this quantity to fluid ounces.
1 pint = 16 fluid ounces
If 2 pints were bought therefore, this would be:
= 2 * 16
= 32 fluid ounces
32 fluid ounces cost $3.20.
Cost per fluid ounce is therefore:
= 3.20 / 32
= $0.10 per fluid ounce
