If Jennifer doubled the money that she has in her account now and then took out $50, she would have enough left in her account to buy a new bike that costs $299. Write and solve an equation to determine how much money Jennifer has now.

Answer:

Something like 2x-50
\geq $299

Explanation:

Because when she doubles the number, that means it is multiplied by 2, but the number she has is unknown, so it's x. Then she takes $50, which means you have to subtract from the 2x. I put the
\geq because technically, the variable could be any number and you could still buy the $299 bike. But if you want an exact answer for the x would be $174.50. :)
