Explanation of Solution

Given information:

Bonus for holiday $\$250$

Amount earns per week $=\$400$

Calculation:

Total amount earns after w weeks $=650w\text{ dollars}$

  $\begin{array}{l}w=4\Rightarrow 650(2)=2600\text{ dollars}\\ w=12\Rightarrow 650(2)=7800\text{ dollars}\\ w=36\Rightarrow 650(2)=23,400\text{ dollars}\end{array}$

Hence,

The amount earns $4,12\text{ and 36}$ after weeks is $2600\text{ dollars,}7800\text{ dollars, }23,400\text{ dollars}$

respectively.
