A.) 11 hours

B.) 15 hours

C.) 5 hours

D.) 19 hours

Answer 1

The answer is B. because he got 25 dollars for doing the lawn. So               119.85-25=94.85. And 94.85/6.35= how many hours or 14.9370079. So 14.9370079 rounded is 15. So your answer is 15 hours. B.)

Answer 2

$119.85 is the total amount he earned in 2 weeks
He mows his neighbor's lawn each week for $25...So if he mows for 2 weeks it should be
$25×2=$50
Darian gets paid $6.35 an hour to help out at his dad's shop...
Let X be the number of hours Darian worked at his dad's shop in the two weeks
So we can now make an equation to find X

(X×$6.35)+($25×2)=$119.85
(X×$6.35)+$50=$119.85
X×$6.35=$119.85-$50
X×$6.35=$69.85
X=$69.85÷$6.35
X=11

Therefore the number of hours Darian worked at his dad's shop in those two weeks is 11
