As a project manager at a construction firm, you need to calculate individual worker efficiency. An experienced concrete finisher can lay a standard concrete slab in 3 hours alone. When paired with a new trainee, they lay the same size slab together in 2 hours. If $t$ represents the hours it would take the trainee to lay the slab alone, which of the following equations correctly recalls the setup for this work application by equating the sum of their individual hourly rates to their combined hourly rate?

A construction site supervisor is training a new team on how to estimate the time required to lay concrete slabs for a housing project. To set up the necessary calculations, match each mathematical term used in work application problems with its correct professional definition.

To calculate how many hours $t$ it takes a junior mason to lay a concrete slab alone, given that an experienced mason takes ${}3$ hours and they finish in ${}2$ hours together, a project manager should use the equation ${}3 + t = 2$.

A construction site foreman is calculating the time it takes for a junior mason to complete a concrete slab project alone. The foreman knows an experienced mason takes 3 hours, the junior mason takes $t$ hours, and together they take 2 hours. Arrange the steps in the correct order to solve the resulting rational equation for $t$.
