To compute Raquel's wage for each yard she mows, we need to find out how much she earns per yard. She earns $75 for mowing 8 yards.
To find her wage per yard, we can set up the following equation:
\[ \text{Wage per yard} = \frac{\text{Total wage}}{\text{Number of yards}} = \frac{75}{8} \]
In the answer options you provided, this can be represented by:
\[ \frac{75}{8} = x \]
Where \( x \) represents her wage per yard.
So the correct choice is:
Start Fraction 75 over 8 End Fraction equals Start Fraction x over 1 End Fraction.
