1. An employee at a restaurant prepares sandwiches and salads. It takes the employee 1.5 minutes to prepare a sandwich and 1.9 minutes to prepare a salad. The employee spends a total of 46.1 minutes preparing $$x$$ sandwiches and $$y$$ salads. Which equation represents this situation?

   • $$1.9x+1.5y=46.1$$
   • $$1.5x+1.9y=46.1$$
   • $$x+y=46.1$$
   • $$30.7x+24.3y=46.1$$

2. The length, $$y$$, of a white whale was 162 centimeters when it was born and increased an average of 4.8 centimeters per month for the first 12 months after it was born. Which equation best represents this situation, where $$x$$ is the number of months after the whale was born and $$y$$ is the length, in centimeters, of the whale?

   • $$y=162x$$
   • $$y=162x+162$$
   • $$y=4.8x+4.8$$
   • $$y=4.8x+162$$
