John is a quarterback. this year, he completed 350 passes, which is 70, percent of all the passes he's attempted this year. how many passes has john attempted this year?

He attempted 500 passes since you divide 350 by 7 which, would give you 5 then, you would multiply it by 100 therefore, it gives you 500

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
