5. An individual goes to a restaurant and buys 4 Chicago dogs and 3 milk shakes for a price of $33. That same day, another individual goes to the restaurant and buys 2 hot dogs and 1 milkshake for $15. Write a system of equations that represents the relationships between Chicago dogs, milk shakes, and the total cost.

What does the solution to the system represent in the context of the problem? (You don’t need to solve the system to answer this!)

you probably already have the answer but anyways it's b. 15.0

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
