Firstly, we know that for every 1.5 hours, there is 360 square feet painted. To find how much can be painted in 1 hour, we need to find the half-hourly rate, by dividing 360 by 3, to give us 120 square feet. We then take this away from 360 to give us the hourly rate, which is 240 square feet per hour.
You could do : Johnny was financing a limited editions Xbox One S. The price was $420 and he put down 40%. How much is left to be financed? dp=420(40/100)=16800/100=168 then you would subtract 420-168 which would give you 252 ;) good luck !!
