We use different types of formulas to solve the algebra questions. The algebra questions can be solved in an easy way by simply applying the formulas that are given to us. Following are some of the examples which are based on this concept.

Number of dollars made in first week = 132 dollars

Pay rate = Money gained/ Working hours = 132/22 = 6 Dollars per hour

Number of hours John worked in the next week = 15 hours

The Amount of money made by John = (Number of working hours) times (Pay rate)

= (15) times (6)

= $90.

R = 6 %

T = 5 years

We have a formula to find the simple interest that is

Simple interest = PRT/100

Now we can plug the values into this formula

Simple interest = 4000 * 6 * 5/100 = $1200
