Answer and Step-by-step explanation:
First, you need to make the function to represent the information given.
We start with 70,000 in the account, and have an interest rate of 6.2%.
We want to know how long it will take to get $223,200.
The equation for simple interest is:
A =
Where A is the total amount, P is the principle amount of money, r is the rate, and t is the time.
Now, we plug in the values and solve for t.
t = 0.353
Multiply by 100 to get the years.
t = 35.3
So, it will take Allison 35.3 years to get 70,000 dollars to 223,200 dollar with an interest rate of 6.2%

Answer: y=3/2x
Step-by-step explanation:
First, to find the equation, we can figure out that the cost depends on how many tickets are bought. We can use cost as our y and # of tickets as our x.
An equation in slope intercept form is as follows:
y=mx+b
To get our slope, we must figure out the relationship between the cost and the number of tickets, or the y and the x.
We can use the slope formula, , to find the slope, m.
=
Thus, the slope of the equation is 3/2, making our final equation be y=3/2x.
