1.35x4
=140
Because 媽媽買4合35元的朱古?=35+35+35+35=4*35
2.850*(100%-25%)
=850*75%
=850*75/100
=212.5*3
=637.5
Because 100% is the natral price's persentage then natral price minus 25% of the natral price is 75%,so the natral price(850) times 75%= 637.5
3.600x95%x80%
=600*95*80/100*100
=6*95*80/100
=6*95*4/5
=6*19*4
=456
600*95%is the price that小志 uses for buying the car,then times the price(600*95%) to 80%( 8折)=$456
