First, we need to solve for t.
Inverse operation of multiplication (75*t) is division. Thus, we need to divide each side of our equation by 75 to solve for t.
75t/75= 300/75
The two 75's cross out.
t=300/75
Now we divide to solve for t.
300/75=4
t=4
Thus, t equals 4.
Our unit per hour is 4.
Our unit rate: 75
