Calculate the following equation: Tim and Jim working on a production line can assemble 30 toy cars between them in one hour. Tim can assemble one more car than Jim in 10
minutes. If Tim worked at twice his rate and Jim at thrice his rate, then the number of toy cars they could assemble between them in one hour
is:

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.
