Suppose you receive $100 for a graduation present, and you deposit it in a savings account. Then each week thereafter, you add $5 to the account but no interest is earned. The amount in the account is a function of the number of weeks that have passed. Create an equation that represents that situation.

A town's population increases at a constant rate. In 2010 the population was 53,000. By 2012 the population had increased to 78,000. If this trend continues, predict the population in 2016. The population will be Number in 2016. D

For the given scenario, identify the type of growth as linear, exponential, or neither. Ephraim owns a hotdog stand. He has found that his profit, Pn, is represented by the equation P₂ = -n²+58m+77. Where n is the number of hotdogs sold.

Conner’s car is worth $24,578. Each year the car’s value decreases by $1,345. Create an equation to describe how much money the car will be worth after a set amount of years. Write the equation for this problem in function notation. Then interpret how much money his car will be worth after 4 years. Make sure to define your variables and show all of your work.

Write an equation to represent the relationship. Define your variables clearly.  A recent study on cost of attending a public four-year institution shows that between the academic years ending in 1989 and 2016 the average annual growth rate for the cost was 2.6% per year.  In 2017 the cost to attend a public four-year institution was about $10,000.

A car is worth $5600 when it is 7 years old and $4500 when it is 11 years old. What is a formula, in point slope form, that models this situation?

The number of hours of video uploaded to YouTube per minute is shown in the table below. Year # of hours of video uploaded per minute 2007 6 2008 10 2009 20 2010 24 2011 48 2012 60 2013 100   Let y be the video upload rate at x years since 2005.   Construct a scatterplot by hand.               Is the relationship linear or exponential?  Increasing or decreasing?   Write an equation modeling the number of hours of video uploaded per minute if the initial number of hours is 2.6 and it increases by 59%.     Use your equation to find the number of hours uploaded in 2015.

You borrow $10,000 into an account that earns 4.5% interest each year. Give the equation of the line and give the total amount you owe have after 30 years.

A $27,000 car has a resale value of $19,000 five years after it was purchased. Assuming the value of this car depreciates linearly, estimate the value of the car 8 years after it was purchased. Enter number only; if your answer is $12,345, enter 12345.

How can you tell if an equation is an "and" or an "or"?
