Answer:
If i did my math correctly, It should be 3 ppl
Step-by-step explanation:
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.
X + 17 +3x -15
x +3x = 4x
17-15 = 2
which becomes 4x +2 so it is true
After 9 days, they will both have watched 18 episodes.
