Knowing that 50 tickets is $37.50 how much is 40 tickets

30

37.50 ➗ 50 =.75.75 ✖️ 40 = 39

From this information we know that the price of 50 tickets is 37.50 dollars.

Now we need to find the price of one ticket only so:

50 = 37.50

1 = X

Where X is the price of one ticket. Let us now cross-multiply this equation. It will give us:

50X = 37.50

X = 37.50/50

X = 0.75

So 1 ticket will cost 0.75 dollars.

How about 40 tickets?

We simply multiply 40 by the price of the 1 ticket, so:

40 * 0.75 = 30

Therefore the price of 40 tickets is 30 dollars.
