1. An airline knows that only about 75% of those who make a reservation actually buy a ticket. At this rate, how many reservations should the airline accept to fill a plane with 180 seats?
2. Safe Side Banks pays an interest rate of 8% per year on certificate accounts. How much money must be put into an account to earn $60 in one year?


Sagot :

We have to use proportion to solve this problem.
75% -------------------180
100% ---------------------x
crossmultiply
75*x=100*180
75x=18000           /:75
x=240 - its the answer

We have similar problem here
8%---------------------60$
100% ------------------x
crossmultiply now
8*x=60*100
8x=600        /:8
x=75 - its the answer
