Cost of the meal ordered by Mr. Rodriguez = $6.25
Cost of the meal ordered by Mrs. Rodriguez = $7.50
Cost of each pizza ordered by the two children = $4.99
Then
The cost of the 2 pizzas ordered by the 2 children = (2 * 4.99) dollars
= 9.98 dollars
So
The total cost of the orders = (6.25 + 7.50 + 9.98) dollars
= 23.73 dollars
Percentage of tip on the bill = 15%
Then
Amount of tip paid = (15/100) * 23.73 dollars
= 355.95/100 dollars
= 3.56 dollars
Percentage of tax paid on the bill = 7.25%
Amount of sales tax that was paid = (7.25/100) * 23.73 dollars
= 172.04/100 dollars
= 1.72 dollars
So
The total bill that was paid = (23.73 + 3.56 + 1.72) dollars
= 29.01 dollars
You can choose from 20 students for the first student, 19 for the second, 18 for the third, ..., 14 for the seventh student.
That gives you 20 * 19 * 18 * 17 * 16 * 15 * 14.
That number would allow you to write the students in different order. Since order here does not matter, any group with the same students in any order is the same group, you need to divide by the number of way you can order 7 items. Divide by 7 * 6 * 5 * 4 * 3 * 2 * 1
(20 * 19 * 18 * 17 * 16 * 15 * 14)/(7 * 6 * 5 * 4 * 3 * 2 * 1) = 77,520
Answer: 77,520

EXPLANATION
Let us find the gradient of the line:
by rewriting it in the slope intercept form.
We divide through by 4 now;
This is now in the form;
where
is he slope.
This implies that the slope of the line that is perpendicular to this line will be the negative reciprocal of .
Thus the perpendicular line has slope,
.
Let the perpendicular line have equation,
When we substitute the slope we have;
We substitute the point. 
to find c.
We substitute c to obtain;
Or
I think it should be option d
