Mathematical modeling is about constructing one or two equations that represent real life situations. What are these math models used for? Provide at least two equations that can be used in the real world. For example: The equation ?=30ℎ+1000s=30h+1000 can be used to find your salary given the fact you earn a fixed salary of $1000 per month, plus $30 per hours.
Here srepresents the total salary and
h
is the number of hours you worked.
