the greens family they had 8 people plus 2 they r going to disenyland they have $3.40 and each person cost 38 cents will they hav enough money to go to thier destionation please explain

38*10=3.80 they need 40 more cents

8ppl + 2 ppl = 10
10ppl * 38cents = 3.80
3.80  3.40 = 40cents
therefore they are short 40 cents and they need to have a fundraiser and raise 40 cents more or they are out of luck! 
for example the greens family they had 8 people plus 2 they r going to disenyland they have $3.40 and each person ... 38*10=3.80 they need 40 more cents ...
