David recycles 5 cans every week. which expression shows the total number of cans he recycles in w weeks? a.5w b. w/5 c.5 + w d.5 + 5w

A because 5 per week so 10 in two weeks etc...so 5 per (w) any number of weeks
hope i help

The answer would be option A 
because if you know that David recycles 5 cans a week every week that the week would turn into w and 5 would stay the same so when you put 5 and w (week) together you would get 5w 
(i am not sure if that is right thought i am taking a test with the same question)

p.s. sorry if i confused you i don't really know how to explain it

Ai think i dont know for sure i remember doing it
