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(

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

final answer is : )

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
