<em>*To solve an inequality, it's the same as if you were solving an equation: Isolate the desired variable to one side to solve.</em>
Firstly, subtract 15 on both sides:
Next, you are going to divide both sides by -30. Since you are dividing by a <u>negative,</u> you are going to flip the inequality symbol. <u>Your final answer will be: </u>
Answer:
The correct answer is v(t) = (principal × time × 0.02) if calculated simply and v(t) = Principal × where v(t) is the interest after t years .
Step-by-step explanation:
Principal amount invested by Shota is $2000.
Interest is earned at 2% per year.
Time for which the principal is invested is t years.
Therefore let the total interest be v(t) dollars in t years.
Case 1: Simple Interest.
v(t) = (principal × time × ) = (2000 × t × 0.02) = 40t
Case 2: Compound Interest.
v(t) = Principal × - Principal = 2000 ×
- 2000.
