Question 1093371
<br>You will need a scientific calculator or some similar tool to do the calculation.  Just plug the given value of t in the expression and evaluate.<br>
And, by the way, you haven't shown the formula correctly.  The exponent should be 0.04t, not 0.4t.  The 0.4t exponentn(corresponding to an interest rate of 40%) gives an unreasonable answer of over $2 million.  The correct 0.04t exponent gives a reasonable answer of a little over $9000.
