Calculating the numeric value of the given function, it is found that Rob will have $2,603.16 in his account in one year.
To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the expression for the amount that he has into his account after w weeks is given by:
A(w) = 0.04w² + 45w + 155.
One year has 52 weeks, hence w = 52, and the amount is given finding the numeric value as follows:
A(52) = 0.04(52)² + 45(52) + 155 = $2,603.16.
Rob will have $2,603.16 in his account in one year.
