First, we need to calculate the cost of the sale tax. To do it, we are going to convert the sale tax from percentage to fraction by dividing it by 100, and then we are going to multiply the cost of the DVD by the sale tax:

Now, we can multiply the cost of the DVD by the sale tax to find the cost of the sale tax:

Now that we know that the sale tax is $1.26, we are going to add the cost of the sale tax to the cost of the DVD and check if that sum is less or equal than Torri's money (20$):

Since $19.26
$20, we can conclude that Torri has enough money to buy the DVD. In fact, Torri will end with a change of $0.74 after buying the DVD.

Grade 11: 41
Grade 12: 30
Required
Determine the domain and the range
The domain and range of a function is represented as thus (x,y)
From the given parameters;

Remove "Grade" to represent as only digits

Split to x and y values:
<em>Where x = domain and y = range</em>


<em>So, from the list of given options; option C answers the question.</em>
Answer:
The class width is 
Step-by-step explanation:
From the question we are told that
The upper class limits is 
The lower class limits is 
The number of classes is 
The class width is mathematically represented as

substituting values



Since
This is an odd question because it's a little subjective, but, for me, I would choose x from the second equation because you could simply add 12y to both sides, then divide by 3. It has the added benefit of not having any decimals/fractions, or negative values, which would be nice for substitution.
It’s the combination of 6/7
