1)      Five less than a number is greater than 10.  

This is an inequality problem.  Write inequality statement for this problem and then solve the inequality.  Include a description of what numbers are part of the solution set for this problem in your Findings Statement.

 

2)      Four more than three times a number is equal to 27. 

Write the equation for this problem using X as your variable and then solve the equation for X.  Write a Findings Statement with your solution for X. 

 

3)      You rent a car for a flat fee of $100 plus 19 cents per mile.  Write an equation for the Rental Fee with X as the variable equal to the number of miles driven. The equation should be in the form, Rental Fee = ------.  

Then solve the Rental Fee for the cost of a rental and driving 50 miles.  Write a Findings Statement for your solution.

 

4)      Find the Interest and Maturity Value of a $2,400 simple interest loan for 2 years at 10% per year.  

Interest is the amount charged for borrowing $2,400.  Interest Percent must be converted to a decimal to use in calculations.   Include how you converted percent to a decimal in explanation.  

The time needs to be in years to agree with the interest rates which are stated on a yearly basis.  

Maturity Value is the total amount that must be paid back to the lender.  Answers must have the proper units to be correct.

 

Use these formulas and show them in your solution, Interest = Principal X Rate X Time and Maturity Value = Principal + Interest.
