Step-by-step explanation:

Here is the complete question

Samantha invested $660 into an account that paid 3.5% interest compounded annually. Samantha did not make any additional deposits or withdrawals

What is the total amount of interest paid by this investment at the end of five years?

A- $115.50

B-$783.87

C-$123.87

$2,755.50

Interst = future value - amount invested

amount invested = $660

Future value = A( 1 + r)^n

FV = Future value  

P = Present value  

R = interest rate  

N = number of years  

$660 x ( 1.035)^5 = $783.87

Interest = $783.87 - $660 = $123.87

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
