The mark family booked a vacation that will cost 2,350. their travel agent charges a 3% fee. how much will they spend altogether on their vacation

The Mark family will spend $2,420.50

Work:
Use proportions.
x. 3
=
2,350. 100

Cross multiply
2,350 x 3 = 7050
100 multiply x = 100x
7050 divided by 100 = 70.50
x = $70.50
Fee: $70.50
Vacation cost: $2,350
$2,350 + $70.50 = $2,420.50

Ithink the answer is c just trying to others
