Best ResponseYou've already chosen the best response.1`a large latte costs 2 dollars more than a medium latte` so L = M+2 agreed?

Best ResponseYou've already chosen the best response.1` medium latte costs 2 dollars more than a small latte` using the variables I set up, what equation do you get?

Best ResponseYou've already chosen the best response.1S = x M = x + 2 L = 2 + (x + 2) or 4 + x

Best ResponseYou've already chosen the best response.1S = unknown (not x) M = S + 2 L = M + 2 = (S+2) + 2 = S + 4 `12 small lattes cost 2x dollars` 12S = 2x S = (2x)/(12) S = x/6 `how much will 5 large and 7 medium lattes cost?` 5L + 7M = 5(S+4) + 7(S+2)

Best ResponseYou've already chosen the best response.1the next step is to plug S = x/6 into 5(S+4) + 7(S+2)

Best ResponseYou've already chosen the best response.1Do you see how I got 5(S+4) + 7(S+2) ?

Best ResponseYou've already chosen the best response.1\[\Large 5(S+4) + 7(S+2) = 5(\frac{x}{6}+4) + 7(\frac{x}{6}+2) \] \[\Large 5(S+4) + 7(S+2) = 5(\frac{x}{6})+5(4) + 7(\frac{x}{6})+7(2) \] \[\Large 5(S+4) + 7(S+2) = \frac{5x}{6}+20 + \frac{7x}{6}+14 \] I'll let you simplify
