Question

A book store is hosting a party.The tickets to the event must be ordered ahead of Time and are 1.50 for children and 2:50 for adults.So far 45 children tickets have been sold, which is 60% of the total tickets.How many tickets have been sold so far?

Answer 1

Let
`x` be the number of tickets sold so far. We know that

`x\cdot(60)/(100)=45 \iff x=(45\cdot 100)/(60)=75`

So, 75 tickets have been sold so far, 45 of those are children tickets and the remaining 30 are adult tickets.
