9 x 0.55 = 4.95, which can be rounded to the ones place.
5 books remain.
It's Feedback A. B is wrong because natural numbers would be reversed with whole numbers, and c is wrong because irrational numbers would be outside.
Hello!
First, we need to find the unit rate.
72 divided by 2 = 36.
36 x 9 = 324.
There were 324 pieces of paper to start with.
Hope this helps, ~Pooch ♥
(28) 2x+10+x-4=21
(29) 3x-16+4x-8=60
(30) 2x-8+3x-10=17
SI = PRT /100
1. SI = 400*5*1/100
= 2000/100
= $ 20
2. SI = 1000*8.5*3/100
= 25.5*1000/100
= $ 255
3. SI = 200*9*1/2*100
= 900/100
= $9
4. SI = 20000*12*3/100
= 200*12*3
= 7200
5. SI = 1200*4.5*6/12*100
= 4.5*6
= $27
Amount to pay = Principal + SI
= 1200+27
= $1227 ( But this answer isn't there in the options )
