Question

the 20 - pack container sells for $5.49. what is the unit rate in dollars per pack? round your answer to the nearest cent.

Explanation:

Step1: Recall unit rate formula

Unit rate is total cost divided by number of units. So, unit rate \( r=\frac{\text{Total Cost}}{\text{Number of Packs}} \)

Step2: Substitute values

Total cost is \(\$5.49\), number of packs is \(20\). So \( r = \frac{5.49}{20} \)

Step3: Calculate the division

\( \frac{5.49}{20}= 0.2745 \)

Step4: Round to nearest cent

Nearest cent means two decimal places. \( 0.2745\approx0.27 \) (since the third decimal is 4, which is less than 5, we round down the second decimal)

Answer:

\( \$0.27 \) per pack
