The equation for the first option is Y=10x + 200
The equation for the second option is Y=30x + 100
X = one month
To find when they would be the same about you have to set the equations equal to each other
10x + 200 = 30x + 100
-10x -100 -10x -100
100= 20x
5 = x
After five months she would save the same amount. To find how much is saved you have to plug in 5 for x in one of the equations. You can always double-check 5 by plugging it in both equations and making sure you get the same answer
Y= 10(5) + 200 = 250
Y= 30(5) + 100 = 250
She would have saved $250 after five months by using either method
Answer:
b. 13 hour, 20 min
Step-by-step explanation:
When it is 4:00 a.m. in Halifax, it is 1:00 p.m. in Karachi, this means Karachi is 9 hour ahead of Halifax.
When it is 9:00 a.m. in Karachi, it is 5:00 a.m. in Warsaw, this means that Warsaw is 4 hours behind Karachi.
She arrived to Karachi at 3:00 pm, Tuesday. Local time. When is 3:00 pm in Karachi is 11:00 am in Warsaw.
The difference between 9:40 am, Monday and 11:00 am, Tuesday, both in Warsaw local time is 13 hour 20 min.
54=.9x Solve for x. x=54/.9=60
You’re answer would be x=7
