Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.

Elena's car: 7000 + 21000t

Marc's car: 20000 + 11000t

To find at what time t they are equal, set these two expressions equal to each other and solve for t.

7000 + 21000t = 20000 + 11000t

13000 = 10000t

t = 1.3 years from now

So first, find out the total amount of money you make in 3 months.

If you make 1200 dollars a month, then in 3 months, you can make 3600 dollars. This is because 1 month salary + 1 month salary + 1 month salary = 3 month salary, and 1 month salary = 1200. So 1200 + 1200 + 1200 = 3600.

Since you're saving 2/5 of that, the simplest method to do this is to divide by 5, to find 1/5 of 3600, then multiply by 2 to find 2/5.

3600/5 = 720

720 * 2 = 1440

So you can save $1440 in three months.

Mumz [18]

Answer: I believe that it might be $1.00


Step-by-step explanation: Well the problem doesn’t tell you how much money he HAD, so if you do 1/3+4/6 you should get 6/6 or 1 as the amount that Lane had.
