2071.5 - 307.5 ( you subtract since you only need to know the number of adults)
1764
1764/10.5 (you divide since each adult is 10.5$)

Formally, you'd read

as "

is an element of the set of real numbers," which is a fancy way of saying that

can be any real number.
Either the second or third. I think the third since the second can be proven with the given info, and then you just need to know another angle from each triangle is congruent. also, its worth knowing that it is also possible to prove similar triangles with just angle angle, since that would automatically make the last angles equal.
