At the city museum, child admission is $5.30 and adult admission is $9.00 . on sunday, 152 tickets were sold for a total sales of $1138.60 . how many adult tickets were sold that day?

90 adult tickets.
You must set up a system of equations and solve.
5.3x + 9y = 1138.6
x + y = 152

When you solve for y (adult tickets), you get 90.

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.
