I believe that the answer you're looking for is B. h+(h+2.5)=22.
h+(h+2.5)=22
h+h+2.5=22
Combine like terms.
2h+2.5=22
Subtract 2.5 from both sides.
2h=19.5
Divide both sides by 2.
h=9.75
Now let's check the work by plugging 9.75 into the equation.
9.75+(9.75+2.5)=22
9.75+9.75+2.5=22
22=22
So we now see that the answer choice B. Is correct! And William worked 9.75 hours. I hope that you found this helpful!
