Henry has $70 in a savings account that earns 10% interest per year. The interest is not compounded. How much interest will he earn in 5 years? Use the formula i=prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.$_____
Q. Henry has $70 in a savings account that earns 10% interest per year. The interest is not compounded. How much interest will he earn in 5 years? Use the formula i=prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.$_____
Calculate Interest Rate: Henry's got $70 in the bank, and it's earning 10% interest each year, not compounded. So, we gotta figure out the interest after 5 years.
Convert Interest Rate to Decimal: First, let's convert that 10% interest rate to a decimal. So, 10% is like 10010, which is 0.10.
Use Interest Formula: Now, we use the formula i=prt to find the interest. We plug in p=$70, r=0.10, and t=5 years.
Calculate Interest: Let's do the math: i=70×0.10×5.
Final Interest Calculation: So, i=$35. That's the interest Henry will earn in 5 years.
