Harry Potter has a large amount of money in his vault at Gringotts. He wants to use some of it to buy his friends new broomsticks. He wants to buy between 8 and 15 broomsticks. Each broomstick costs 150 Galleons, what is a reasonable Domain and Range for the situation?

Domain is 8 to 15 broomsticks

Range is 1,200 to 2,250 Galleons

Step-by-step explanation:

Here, when we talk of the domain, we are simply referring to the range of values of the number of broomsticks to be bought which is between 8 and 15

When we talk of the range, we are talking of the amount these broomsticks will cost

The cost for 8 broomsticks will be 8 * 150 = 1,200 Galleons

15 broomsticks will cost 15 * 150 = 2,250 Galleons

The range here will thus be 1,200 Galleons to 2,250 Galleons

=

x=0.8898305 is the answer to that equation
