To find an equation that computes Raquel's wage for each yard, we need to represent her total wage of $75 for mowing 8 yards.
We can use the formula for the unit rate, which is:
\[ \text{Wage per yard} = \frac{\text{Total Wage}}{\text{Number of Yards}} \]
This can be expressed as:
\[ x = \frac{75}{8} \]
Where \(x\) represents the wage per yard.
The equation that correctly represents this relationship is:
B: \(75/8 = x/1\)
This equation rearranges to show that Raquel earns \(75/8\) dollars per yard. Thus, option B is the correct choice.
