the sale price of the surfboard issssss..............
260 seats in economy class, 100 in business class
The ratio of economy class to business class is 13:5
13+5 = 18 (total seats in the ratio)
360/18 = 20 (to see how many multiples of the ratio there are)
20*13 economy = 260 economy
20*5 business = 100 business
X = boys
2x+24=5x
Subtract 2 x from each side
24=3x
X=24/3 = 8
there are 8 boys
