Mario collects seashells and sells them to tourists. The function s (t) approximates how many seashells Mario collects per hour. The function W (h) represents the number of hours per week Mario spends collecting seashells. What are the units of measurement for the composite function s (W (h)) ?

Shells per week is the unit for this composite.

Step-by-step explanation:

For example, if my s (t) function is s (t) = 4t, this says that I can collect 4 shells in one hour. If my W (h) function is W (h) = 3h, this says that I work 3 hours per week collecting shells.

If you can collect 4 shells in 1 hour and you work 3 hours per week, you collect a total of 12 shells that week.

The units are shells per week

Answer with explanation:

It is given that Mario collects Seashells.

s (t) = Number of seashells collected by Mario per hour

W (h) = Number of hours per week Mario spends collecting seashells.

s[W (h) ]=s[Number of hours per week Mario spends collecting seashells]

= (Number of Seashells Collected per hour) [Number of hours per week Mario spends collecting seashells]

=Number of Seashell Collected by Mario in a week per hour
