Answer:

b and c

Step-by-step explanation:

They both follow the formula of a linear function: y = mx + c, where m is the gradient and c is the y-intercept.

When you rearrange:

a. y = 60/x (this is a reciprocal function)

b. y = x - 1 (says that this linear function has a gradient of 1 and cuts the y-intercept at (0,-1))

c. y = 3x/2 -5/2 (says that this linear function has a gradient of 3/2 and cuts the y-intercept at (0, 5/2))

The principal, P = $50,000

Interest rate, r = 4% = 4/100

r = 0.04

Number of times intesrest is compounded per year, n = 1

Total amount is calculated below:

\begin{gathered} A=P(1+r)^t \\  \\ A=50000(1+0.04)^{16} \\  \\ A=50000(1.04)^{16} \\  \\ A=\$93649 \end{gathered}

Total amount earned after 16 years = $93649
