For this case we have to:
x: Let the variable representing the unknown number
We algebraically rewrite the given expression:
Eleven more than four times a number, is represented as:
The number less 7, is represented as:
Thus, the complete expression is:
We subtract x from both sides of the equation:
We subtract 11 from both sides of the equation:
Equal signs are added and the same sign is placed:
We divide by 3 on both sides of the equation:
Answer:
To answer this question we will use the following formula for compounded monthly interest:
where A₀ is the initial amount, r is the annual interest as a decimal number and 12 is the number of years.
Notice that:
Therefore, substituting t=42, r=0.02, and A₀=120000 we get:
Simplifying the above result we get:
Answer: $277,769.75.
