You want to buy an MP3 player. Your Aunt paid you $20 to mow her lawn and you earn $5 each week 1. Write an equation in Slope-Intercept form that represents y total amount saved and

x is number of weeks
y=125x+5
y=20x+125
y=5x+20

2. Interpret the y-intercept
$5 the amount you start with before mowing lawns
$20 the amount you saved mowing your aunt's lawn
$125 the amount you need to earn

3. If the MP3 player costs $125, how many weeks until you can afford to buy it?
21 weeks
105 weeks
25 weeks
