Last night Jasmine and Jay amount combined is $150+$130=$280
amount donated to charity is 1/4 of $280= $70
amount spent at an amusement park is` 40/100 x $210= $84
the remaining money = 280- (70+84)= $126
35% of their original amount is 35/100x$280=$98
so Jay's claim is not correct because the remaining money is $126 and not $98 as she Jay claims.
