Answer 1

I think the corcorrect answer is 3690

Answer 2

Note!! if someone else answers, their answer is probably correct. I don't know functions that well. also, I'm assuming here that Samuel and Gordon are the same person.

Gordon/Samuel pays: 3690$

independent variable: the amount of TVs you buy

dependent variable: the cost for each tv

function: f(x) = 1200x + 90

solve the function: hopefully someone else can answer this!

if I made a mistake or misunderstood something, please let me know!
