Today is actually the 210th day. They will meet again in 209 days (the 210th is the day they deliver together so I don't count it, but you can totally count it if you want to)
The constant of proportionality should be 45 miles per hour, and the car should travel 135 miles in three hours.
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.
The answer is easy
So we need to fund m2NLM
The answer is c
It would b 9 x (-3^(x-1))
