Answer:
x > 11
Step-by-step explanation:
Given:
Where:
To find the number of weeks he must save before he can buy his bike, we need to find the value of x
[tex]130 + 20 x > 350[/tex]
Subtracting 130 from both sides
[tex]20 x > 350 - 130[/tex]
Simplify
[tex]20 x > 220[/tex]
Divide both sides by the coefficient of x
[tex]\frac{20x}{20} > \frac{220}{20}[/tex]
[tex]x > \frac{22}{2}[/tex]
[tex]x > 11[/tex]
Therefore, the number of weeks required to save before he can buy his bike is greater than 11
