t. How much money did he initially place in the account? Round your answer to the nearest dollar. Do NOT round until you have calculated the final answer.
Use the formula for calculating compound interest A=P0ert where A is the unknown, P0=4400, r=0.034, and t=12. Substitute the values into the formula and simplify.
A=4400e0.034⋅12
A=4400e0.408
A=4400(1.503...)
A=6616.75
After 12 years, there will be A≈6617 in the account, rounded to the nearest dollar.
17/100 is the same as 17÷100. 17÷100 =0.17 sqr mile. OR 17/100, the denominator means what place it is in. The denominator is100, so it's in the hundredth place. 0.17
