Answer:
2S + J = 24000
Step-by-step explanation:
let Susan be S
let Jinan be J
they paid 24000
susan paid twice as muh as jinan did
2S + J = 24000
therefore equation is
2S + J = 24000
I'll use my own formula (similar to yours tho)

A=future amount
p=invested
r=rate in decimal
n=number of times per year compounded
t=time in years
so
when will A=2P
subsitute 2P for A
also quarterly means 4 times a year or n=4
and 12%=0.12=r
so

divide both sides by P

simplify


take the ln of both sides



divide both sides by 4ln(1.03)

Answer:
domain = {x|xER}
range = {y|y≥0,yER}
Step-by-step explanation:
|x| means the absolute value which in this case is the distance from 0. On a graph this function would look like a v and would mean it would have infinite x-values since it is opening upwards in both directions.
For the range the vertex of this function is (0,0), if the x-coordinate were 0 the y-coordinate would be 0 because the absolute distance from 0 is 0. for another x-coordinate say -2 the absolute distance from 0 is 2 meaning the y-value is 0 since y=|x|, making the coordinate (-2,2) meaning the range is every y value must be above 0 since there is no way for the y-value to be negative
