Question

What is the unit rate, and which has the better value?

(PLEASE HELP)
17 oz for $2.98
or,
21 oz for $3.50​

Answer 1

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.
