Identify Given Values: Identify the given values from the problem.Principal p = $10Interest rate r = 5% or 0.05 when expressed as a decimalTime t = 3 yearsWe will use the compound interest formula B=p(1+r)t to find the final balance B.
Substitute Values: Substitute the given values into the compound interest formula.B=10(1+0.05)3Now we need to calculate the value inside the parentheses first, which is (1+0.05).
Calculate Inside Parentheses: Calculate the value inside the parentheses.1+0.05=1.05Now we have B=10(1.05)3.
Calculate Exponent: Calculate the exponent part of the expression.(1.05)3=1.05×1.05×1.05We need to multiply 1.05 by itself 3 times.
Perform Multiplication: Perform the multiplication to find the value of (1.05)3.1.05×1.05×1.05=1.157625Now we have B=10×1.157625.
Multiply Principal: Multiply the principal by the result from Step 5 to find the final balance.B=10×1.157625B=11.57625To the nearest cent, we need to round the final balance.
Round Final Balance: Round the final balance to the nearest cent.B≈$(11.58)Spencer will have approximately $(11.58) in his account after 3 years.
