Yes ! By golly, the expressions are equivalent.
Sarah and Noah are both paid for the number of
hours that they work in a week. It doesn't matter
how the hours are spread out during the week.
Only the total number of hours in the week is what counts.
Sarah worked on two days and Noah worked on only
one day, but they both worked the same number of hours,
so they both earned the same total pay last week..
