You have an account with a principal of $200. it pays 8% at the end of every year. calculate the principal at the end of 3 years
Katarina [22]

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. The principal at the end of 3 years is $248.

<h3>What is simple interest?</h3>

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = (P × R × T)/100

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

The principal at the end of 3 years is,

Principal after 3 years = P + (P × R × T)

= $200 + ($200 × 0.08 × 3)

= $200 + $48

= $248

Hence, the principal at the end of 3 years is $248.

Solve for b in the equation: 2b + 3c = 14
bagirrra123 [75]
Remember you can do anything to an equation as long as you do it to both sides

2b+3c=14
minus 3c both sides
2b=14-3c
divide both sides by 2
b= \frac{14-3c}{2}
