Answer: Option 1

Explanation:

I'd say the easiest way would be to find the prize per oz in both options

Option 1: $1.10/12oz = approx 0.092 (so around 9 pennies)

Option 2: $0.98/10oz = 0.098 (also 9 pennies but still slightly more than option 1)

You can check by choosing a random number of oz and multiplying them by the price to see which costs more

ex: 120 oz

option 1 : 10 x 1.10 = $11

option 2: 12 x 0.98 = $11.76
