Question

Write an equation to represent how many plates Ana has left to wash at a particular time after her start at 7:15. Explain your reasoning.

Just give me the answer and a very short sentence of reasoning

Answer 1

Let \( P(t) = P_0 - r \times (t - t_0) \), where \( P_0 \) is the initial number of plates, \( r \) is the rate of washing plates per minute, \( t \) is the time in minutes since 7:15, and \( t_0 = 0 \) minutes at 7:15.

This equation represents the decrease in the number of plates over time based on Ana's washing rate.
