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:
![y=7t](https://tex.z-dn.net/?f=y%3D7t)
Stephanie will buy one shovel that costs $15 dollars, thus our expression now becomes:
![y=7t+15](https://tex.z-dn.net/?f=y%3D7t%2B15)
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
![y=7t+(0.75)15](https://tex.z-dn.net/?f=y%3D7t%2B%280.75%2915)
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:
![y=[7t+(0.75)15]+0.06[7t+(0.75)15]\\\\y=1.06 [7t+(0.75)15]](https://tex.z-dn.net/?f=y%3D%5B7t%2B%280.75%2915%5D%2B0.06%5B7t%2B%280.75%2915%5D%5C%5C%5C%5Cy%3D1.06%20%5B7t%2B%280.75%2915%5D)
Thus the correct option is Option C. 1.06[7t + 0.75(15)]
We translate the data of Mary as (15,90) and (8, 62). In this case, the slope is (90-62) / (15-8) or equal to 4. The equation is y-y1 = m (x-x1) where m is the slope. Substituting, y - 90 = 4 (x-15) or equal to y = 4x + 30. <span> Lisa receives half the base amount that Mary does, but she is paid twice as much per student so the equation that of Lisa is y = 8x + 15.
when x is 20
</span><span>Mary : y = 4*20 + 30 =110
</span>Lisa : y =<span> 8*20 + 15 = 175.
Hence Lisa earns more.</span>
