Ralph deposited $910 in an account that pays 5.2% simple interest for 3 1/2 years What is his ending balance

His ending balance is $1075.62

Step-by-step explanation:

To solve this question, we will simply use this formula;

Simple Interest = P * R * T / 100

where p is the principal amount

R is the rate and T is the time

From the above question, principal p=$910 Rate r=5.2 and Time t = 3 1/2

We first change 3 1/2 from mixed number to either improper fraction or decimal fraction;

3 1/2 = 7/2 = 3.5

We can now go ahead and substitute all our variables in the formula;

Simple Interest = P * R * T / 100

= $910 * 5.2 * 3.5 / 100

= $ 16562 / 100

=$165.62

Simple interest is $165.62

But what we are ask to look for is the ending balance, to get the ending balance, jut add the principal and the interest altogether;

Ending balance = $910 + $165.62

Ending balance = $1075.62
