bazaltina [42]
When you want to find a percent of a number you do this:
given number/ 1   multiplied by   percentage/100

so in this question its a multiple step 

start with finding 25 percent of 4250 which is= 1062.5
so thats how much the discount is so the amount after the 25% discount is:
4250-1062.5= 3187.5

then you have to add 9% due to fees
so you find 9% of 3187.5 which is= 286.875
so you add 286.875 to 3187.5 gives you= 3437.375 in total cost for the vacation package
