Sam ate 2 corn dogs and 5 caramel apples at the fair if corndogs cost $2.25 and caramel apples cost $0.95 cents a piece, what is the ratio of total cost of corn dogs to total cost of caramel apples? write your answer in the form a: b, where a and b are whole numbers.

4.5:4.75

Step-by-step explanation:

What you had to do was times them. So you times 2 by 2.25 because that is how much a corn dog cost and Sam bought 2. And you times 5 by .95 because that is how much a caramel apple cost and Sam bought 5. The 2 corndogs cost $4.50 and the caramel apples cost $4.75. You then put it into a ratio based off total cost of corn dogs to caramel apples and it is 4.5:4.75.  

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
