Rachel wants to buy a bike for $300. She currently has $150 and is saving $10 each week the bike owner is decreasing the price of the bike $15 every week he doesn't sell it how many weeks until rachel has enough money to buy the bike

Answer: it will take 6 weeks until she has enough money to buy the bike.

Step-by-step explanation:

Let x represent the number of weeks until rachel has enough money to buy the bike.

She currently has $150 and is saving $10 each week. It means that the total amount that she would have saved after x weeks is

150 + 10x

The bike costs $300. The bike owner is decreasing the price of the bike $15 every week. It means that the cost of the bike after x weeks is

300 - 15x

For Rachel to save enough money to buy the bike, the number of weeks would be

300 - 15x = 150 + 10x

10x + 15x = 300 - 150

25x = 150

x = 150/25

x = 6
