The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
Answer:I think A
Step-by-step explanation:
Hopefully I am right
It'll be 7 because 3/4 is greater than 1/2 so you round it up.
Answer:
(B) $5.25
Step-by-step explanation:
We can create an equation to represent this problem.
Let's assume
is the cost of a ferris wheel ticket,
is the cost of a snow cone, and
is the cost of a cotton candy.
We bought two ferris wheel tickets, one snow cone, and one cotton candy. After a discount of 6 dollars, the price was 12.75.
This makes the equation 
Since we know the value of each ferris wheel ticket and the snow cone, we can simplify our equation by substituting in these values.

We can now subtract 7.5 from both sides to get the value of
, the cotton candy price.

So the cotton candy cost $5.25.
Hope this helped!
