Answer:
we can see that the second option, 21 oz for $3.50, has the better value because it costs less per ounce compared to the first option.
Explanation:
To calculate the unit rate for each option, we divide the price by the amount of ounces:
For 17 oz for $2.98:
Unit Rate = $2.98 ÷ 17 oz
Unit Rate = $0.175 oz^-1 (rounded to three decimal places)
For 21 oz for $3.50:
Unit Rate = $3.50 ÷ 21 oz
Unit Rate = $0.167 oz^-1 (rounded to three decimal places)
Comparing the two unit rates, we can see that the second option, 21 oz for $3.50, has the better value because it costs less per ounce compared to the first option.
