ough. The inequality below represents x, the number of weeks he must save to have the extra money needed. Which best describes the number of weeks he must save before he can buy his bike?
Leon needs $350 Leon has $130 Leon wants to save $20 per week x = weeks
First, let's place what Leon needs on the left side of the equation:
$350 = ...
We know Leon as $130 saved so far, he plans to save $20 a week. So, what you do here is add $130 to $20x. The reason why x is next to the $20 is because Leon wants to save $20 a week (the x represents the week). The reason why you add 130 is that's what Leon has saved so far. Therefore, the right side of your equation should look like this:
... = 130 + 20x
whereas 130 represents the amount saved so far, 20 represents weekly savings, x represents the number of weeks.
Put the left and right sides of the equation together and you should have:
