What is simple interest?

Back

Simple interest is calculated using the formula: I = PRT, where I is the interest, P is the principal amount, R is the rate of interest per year, and T is the time in years.

Front

How do you calculate the total amount in a savings account after a certain period with simple interest?

Back

Total Amount = Principal + Interest, where Interest = PRT.

Front

What is the formula for calculating simple interest?

Back

I = PRT, where I is the interest, P is the principal, R is the rate (as a decimal), and T is the time in years.

Front

If Divya deposited $8500 at an interest rate of 3.8% for 3 years, what is the interest earned?

Back

Interest = 8500 * 0.038 * 3 = $966.

Front

What is the total amount in Divya's account after 3 years?

Back

Total Amount = Principal + Interest = 8500 + 966 = $9466.

Front

What does the inequality y > 3x - 2 represent graphically?

Back

It represents the region above the line y = 3x - 2, not including the line itself.

Front

How do you graph the inequality @@y ge -rac{1}{3}x + 2@@?

Back

Front

What does it mean if a point lies on the boundary line of an inequality?

Back

If the boundary line is solid, the points on the line are included in the solution set; if dashed, they are not.

Front

Back

It means that three times a number x is greater than seven.

Front

How do you determine if a point is part of the solution set for an inequality?

Back

Substitute the point into the inequality; if it makes the inequality true, it is part of the solution set.
