A geometric series begins with 500 and decreases by 15% successively. Choose
True or False for each statement about
the series.
A. The common ratio is 1.15.
O True O False
B. In the sum formula, a = 500 and
r=0.85.
True False
C The sum, if the series has 5 terms, is
1,854 (rounded to the nearest
integer).
O True False
D The sum, if the series has 9 terms, is
2425 (rounded to the nearest
integer).
True False

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.
