Answer:
Option C) 1.06[7t + 0.75(15)]
Step-by-step explanation:
Lets analyse the given information and 'build-up' our equation step-by-step.
Each plant costs $7 dollars, and Stephani will be buying a few plants. So we can name the number of plants as , therefore we have our first term of our general expression ( ) as:
Stephanie will buy one shovel that costs $15 dollars, thus our expression now becomes:
Now she will be using a coupon of 25% off the cost of the shovel. Therefore the actual cost Stephanie will be paying is % %. Thus our expression will be
Finally we know there is a Sales Tax of % which is equivalent to . Now considering you have a general amount , the Sales Tax is applied as follow: . Similarly then in our case and with the sales tax applied we have:
Thus the correct option is Option C. 1.06[7t + 0.75(15)]
Answer:
is a subset of
Step-by-step explanation:
Required
Difference between subset and proper subset
To answer this question, I will use the following illustration.
In the above sets, set B is a proper subset of set A because all elements of B can be found in A, but not element of A can be found in B.
Set C is a subset of A because
Using the above illustration, we have:
and
is a subset of , because 5 and 8 are in but 2 which ca be found in is not in
