Kate borrowed $400 from her friend. she will repay this amount plus 3 percent simple interest after one year. what is the total amount she will pay her friend? simple interest = p x r x t

$412 i am pretty sure that is right if not i'm sorry but good luck :) 

Okay so clue word is toatl and plus so you going to do
$400+3%+1
400+3=403+1=404 i belive

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.
