Unit price = total price / size
unit price for 25 ounce can :
$4.80 / 25 ounces = $0.192 per ounce

So he has to paint 255 m from the 280 m of paint he has
First divide 255/280 to give you a decimal
You should get .9107

So .9107 times 100
This gives you the percentage which is
91.07%
Now it says round to 1 decimal so it would be
91.1%
