谁帮我解英文数学题
If Wayne gives $250 to Terry, they will have the same amount of money. If Wayne gives 10% of his money to Terry, Terry will have $330 more than Wayne. How much does Terry have?
答
如果W给T $250则两人一样了；如果W把自己的10%给T,则T比W多$330,问原来T有多少$
W-250=T+250
W(1-10%)+330=T+10%W
化简一下
W=T+500
0.8W=T-330
解方程得到W=4150 T=3650
