Answer:
x = 
, y = 2
Step-by-step explanation:
3x + 3y - 7 = 12x + y
6y - 12x - 1 = -45x
(3x - 12x) + (3y - y) = 7
(-12x + 45x) + 6y = 1
-3(-9x + 2y = 7)
33x + 6y = 1
27x - 6y = -21
33x + 6y = 1
60x = -20 -> x = -20/60 = -1/3
-9x + 2y = 7 -> y = 
= 
= 2
Answer:
$1.50
Step-by-step explanation:
1. we know that its $240 per 160 hot dogs
2. make that a ratio - 240:160
3. simplify the ratio so that the amount of hot dogs is at one (so divide both sides by 160)
4. so 240/160 = 1.5 . 160/160 = 1
5. 1.5:1
6. so for every one hotdog, you pay $1.50
