A person invested $130 in an account growing at a rate allowing the money to double every 15 years. Write a function showing the amount of money in the account after t
years, where the annual growth rate can be found from a constant in the function.
Round all coefficients in the function to four decimal places. Also, determine the
percentage of growth per year, to the nearest hundredth of a percent.

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.

150
