John and 3 friends are going out for pizza for lunch. They split one pizza and 4 large drinks. The pizza cost $13.50. The spend a total of $20.50. Find the cost of one large drink.

7 dollars

Step-by-step explanation:

do 20.50 minus 13.50 but you can just take out the .50 because both sides have them and they will cancel out anyways then its just 20 minus 13 and that is 7.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
