The selling price of a scientific calculator is $15. if the markup is 25% of the dealer’s cost, what is the dealer’s cost of the calculator? .

The markup is an integrated cost of the price of a product that goes to the profit of the seller. In this case, a mark up of 25% is added to a calculator costing $15. The total cost then is $15*1.25 or equal to $18.75. In this case, a $3.75 is the profit.

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.
