The weight is proportional to the price. So if 10lb cost $18.24, quarter as much (2.5lb) would cost four times less($18.24÷4=$4.56).
1. 14.3-2*5²÷5=14.3-10=4.3
2. Result is Twenty one
First thing we gotta do is find the unit rate:
800 divided by 2.5 = 320
And now your problem is complete! The unit rate or square foot per hour is 320 square feet per hour!
Hope this helps, if not, comment below please!!!
