类似问题4：“溱潼会船节”开幕式这天，某停车场预计停放的大小汽车共1200辆，该停车场的收费标准为：大车每车次10元，小车每车次为5元，根据预计，解答下列问题：（1）写出开幕式这天停车场的[数学科目]
（1）若小车停放数为x（辆），
则停车场收费金额 y=5x+10×（1200-x）=12000-5x，
且自变量0≤x≤1200；
（2）由（1）式知 停车场收费金额 y=12000-5x（0≤x≤1200），
①若停放的小车辆占停车总车辆的65%时，x=780，此时y=8100，
②若停放的小车辆占停车总车辆的85%时，x=1020，此时y=6900，
又因为 y=12000-5x为一次函数，并且y随着x的增大而减小（根据一次函数的性质），
所以6900元≤y≤8100元；
（3）如果停车场预计收费总额不少于10000元，则y≥10000，
即12000-5x≥10000，
解得x≤400，
所以至多停放400辆．
答：（1）开幕式这天停车场的收费金额y（元）与小车停放数x（辆）之间的函数关系式是y=12000-5x（0≤x≤1200）；
（2）如果开幕式这天停放的小车辆占停车总车辆的65%至85%，收费金额的范围是6900元≤y≤8100元；
（3）如果停车场预计收费总额不少于10000元，则至多停放400辆小车．
