Five tickets to a carnival cost $45. How much would seven tickets cost?

$63

Step-by-step explanation:

In order to solve this problem, we need to find the unit price, which is the price per 1 ticket in this case. To find this, we need to divide $45 by 5 because each ticket is the same amount: $45 / 5 = $9. So each ticket is $9.

Now, we need to find how much 7 tickets would cost. To do this, multiply the $9 / ticket by 7 tickets: $9 * 7 = $63.

Thus, 7 tickets would cost $63.

Hope this helps!

The most appropriate number type will be whole numbers.

Step-by-step explanation:

We have been given that Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. Also, that D(t) models Tanya's remaining distance to walk in kilometers, t minutes since she left home.

We know that time 't' can take any integer value between 0 and 17.

Therefore, the number type that would be most appropriate for domain of d(t) will be whole numbers.
