Question

Uma wants to buy a video game system for $400. She has $50 and is saving $25 each week. Solve the equation 25w + 50 = 400 to find how many weeks w it will take Uma to save enough to buy the system.

Answer 1

Move all terms that don't contain ww to the right side and solve.
w=14

Hope this helps,

Answer 2

First take away fifty from both sides
25w = 350
Divide 25 from both sides
Answer is: w = 14


So, it will take Uma 14 weeks to save enough money to but the video game system.




Hope that helps!!!
