Verified Answer :

Unit rate is per unit; therefore, to determine the rate for one week you must divide each part if the problem by 6, giving you the unit rate which is $18.00 per week.

calculista

we know that

A unit rate is a ratio between two different units with a denominator of one

so

the rate \(\$108\) in \(6\) weeks is not a unit rate

To find the unit rate divide \(\$108\) by \(6\ weeks\)

\(\frac{108}{6} = 18\ \frac{dollars}{week}\)

therefore

the answer is

The unit rate is \(18\ \frac{dollars}{week}\)
