Answer:
4
Step-by-step explanation:
(x)^2+(1/x)^2=18
(x-1/x)^2+2x.1/x=18
(x-1/x)^2+2=18
(x-1/x)^2=16
(x-1/x)^2=4^2
x-1/x=4
First option:
y=money saved
x=number of months
y=30x+500
Second option:
y=50x+200
We have this system of equations:
y=30x+500
y=50x+200
We can solve this system of equations by equalization method
30x+500=50x+200
30x-50x=200-500
-20x=-300
x=-300/-20
x=15
so;
y=30x+500
y=30(15)+500
y=450+500
y=950
Answer; after 15 months, she would save the same amount using either option, the amount saved in either option will be $950.
