Sagot :
Answer:
6.5 weeks without parental help, 3.5 weeks with help from your parents.
Step-by-step explanation:
The Equation is:
Y = 20x
Y = Starting price for bikes
X = # of weeks
Therefore:
$130 = 20x
This can be simplified by solving for x
x = 130/20
x = 6.5 weeks
If your parents gave you $60 to help buy the bike the equation would be written as:
Y = 20x + 60
$130 = 20x + 60
Subtract 60 from both sides to get:
$70 = 20x
Solve for x
x = 70/20
x = 3.5 weeks
