To determine if the pay rates are proportional, we need to calculate the pay rate (dollars earned per week) for each worker.
Worker 1:
Earns $85 in 2 weeks, so the pay rate is:
\[
\text{Pay rate} = \frac{85 \text{ dollars}}{2 \text{ weeks}} = 42.5 \text{ dollars per week}
\]
Worker 2:
Earns $175 in 4 weeks, so the pay rate is:
\[
\text{Pay rate} = \frac{175 \text{ dollars}}{4 \text{ weeks}} = 43.75 \text{ dollars per week}
\]
Now we compare the pay rates:
- Worker 1: $42.5 per week
- Worker 2: $43.75 per week
Since $42.5 is not equal to $43.75, the pay rates are not proportional.
Therefore, the correct response is: No, because the ratios of dollars to weeks are not equivalent.
