Christopher drove 360 miles this week. last week he drove 480 mile. what is the percent decrease in the number of miles christopher drove this week compared to last week

Last week, Christopher drove 480 miles
This week, Christopher drove 360 miles

The difference in miles this week compared to last week = 480 - 360 = 120 miles.

The percentage of decrease in miles compared to last week's  = (Difference in miles ÷ Total miles last week) multiplied by 100 = (120 ÷ 480) x 100 = 0.25 x 100 = 25%

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.
