A compound inequality is an inequality that combines two simple inequalities.
We want to solve for x the following compound inequality
Solving the first inequality for x, we get:
Solving the second inequality for x, we get:
So our compound inequality can be expressed as the simple inequality:
The graph of a compound inequality with an "or" represents the union of the graphs of the inequalities. A number is a solution to the compound inequality if the number is a solution to at least one of the inequalities.
Graphically, we get

Hello!
To find how much money total will be in the account after four years, you need to use the function, , as seen above. In this function, a is the starting value, r is the interest rate, and t is the amount of time (in years).
Before substituting values into the function, we need to convert 3% into a decimal. Remember that all percentages are out of 100, so we divide 3 by 100 and remove the percentage sign, or move the decimal two places to the left.
3/100 = 0.03 | 0.03 is the interest rate.
With all the necessary values, we can find the total amount in the account. In this case, a = 1200, r = 0.03, and t = 4.
y = 1350.610572, which can be rounded to 1350.61 dollars.
Therefore, after 4 years, the total amount in the account will be about 1350.61 dollars.
