How to do i=prt

The video tutorial explains the use of the formula I = PRT to calculate interest. It covers the components of the formula: interest (I), principal (P), rate (R), and time (T). The tutorial provides real-life examples, such as savings accounts and CDs, to illustrate how interest is accrued over time. It also includes a step-by-step example of solving for time when given the principal, rate, and interest. The tutorial emphasizes the importance of converting percentages to decimals and using calculators for accurate results.

What is the primary purpose of using the formula I = PRT in algebra?

• To calculate the area of a rectangle

• To solve quadratic equations

• To determine the interest earned on a principal amount

How is the rate 'R' expressed in the formula I = PRT?

• As a decimal

• As a percentage

• As a fraction

• As a whole number

What is the first step in solving for 'T' in the formula I = PRT?

• Divide the interest by the principal

• Multiply all known values

• Convert the rate to a decimal

If you want to earn $42 in interest with a principal of $350 at a 6% rate, how many years should the money be invested?

• 3 years

• 4 years

• 2 years

• 1 year

What is the importance of isolating the variable 'T' in the formula I = PRT?
