In a sale, normal prices are reduced by 10% nathalie bought a pair of shoes in the sale for £54. what was the orginal price of the shoes?

59.4 because if you take off another 10 percent than add double that you get 59.4

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.
