Answer 1

Given Data:

Cost of the bike is $ 125.

The amount she already has is $ 60.

The amount she saves every week is $ 5.

(a).

The amount to be saved in w weeks will be equal to 5w.

Thus, the required equation can be formed as,

5w+60=125

(b).

The number of weeks can be determined as,

$\begin{gathered} 5w+60=125 \\ 5w=65 \\ w=13 \end{gathered}$

Thus, the required number of weeks is 13.
