Expert Solution

Step 1

Given

Income of a dog's trainer = 1310

Salary used in savings' account = 15% of 1310

Salary used for rent = 310

Salary used for food = 405

Hence total salary used till this point is

$\begin{array}{rcl} 15 % o f 1310 + 310 + 405 & = & \frac{15}{100} \times 1310 + 310 + 405 \\ = & \frac{1965}{10} + 310 + 405 \\ = & 196.5 + 310 + 405 \\ = & 911.5 \end{array}$
