Don and marie like to go to a good restaurant. dinners are $16 to $19 dollars with soup or salad. a beverage is $1.50. dessert is $3.75. if one dinner is $16, the other is $19 and each diner has a beverage and dessert, what will the cost be if a 6% tax is charged and a 15% tip on the pre-tax amount is left? $

16 + 19 + 2(1.50) + 2(3.75) = 45.50now this is before tax

there is a tip of 15%0.15(45.50) = 6.825 rounds to 6.83tip

there is a 6% sales tax45.50 * 1.06 = 48.23

so in total, meal + tax + tip = 48.23 + 6.83 = 55.06 <===

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually

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.
