Answer to word problem

Question

You are renting some tables for a party and have to choose between two different rental companies. The first charges $15per table. The second charges a service charge of $40 plus $11 per table. 

Answer 1

Well, if you needed 2 tables, that would be $15(2), right? Instead, you are paying $15t for t number of tables.

The other company is the same but they charge a flat fee on top of it. 11t + 40. It's not 40t because the $40 isn't per table;it's just charged once.

When they are even, hey, that's what = means.

15t = 11t + 40

15t - 11t = 11t + 40 - 11t

4t = 40

4t/4 = 40/4

t = 10

So, at 10 tables, the cost will be the same for either.
