From all the information given, you're going to have to create two equations and solve accordingly.

If x=cost for one day at hotel; and y=cost for one day at amusement park then,

eq1 : 450=3x+2y; eq2: 700=5x+3y

The total cost of the trip will be number of days spent at each location multiplied by the cost.

If you multiply equation 1 by 3 and equation 2 by 2 and subtract equation 2 from 1, than you will be able to isolate x.

1400=10x+6y

1350=9x+6y

x=$50; then plug back into any equation to find y.

450=3*50 + 2y

y=$150
