Chris needs a graphing calculator for math class. he finds a 60$ model on sale for 15% off. if he decides to buy this calculator, how much will the sale price be?

0.150 x $60 = $ 9.00 Convert 15% into a decimal. 

$60 - $ 9.00 = $51.00 You'll save $9 on the graphing calculater

The sale price will be $51.00

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.
