Answer:
She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:
Step-by-step explanation:
From the question:
Purchasing cost price of the dress = £30
However, this cost (£30) was after a 25% Sales Discount
It, therefore, implies that £30 is equal to 75% of the cost price
75% of the original cost price = £30
100% of the original cost price = (30 x100%)/75%
Original cost price = £40
Therefore the 25% discount / savings on the cost
= £ (40-30)
= £10
She saved £10 by buying the dress at £30 instead of the original cost of £40
Answer:
7/8 is nearly 1, and 8 1/10 is obviously 8.1 (1/10), which is rounded to 8. So th expression that best estimates the products of those numbers is D, 1 * 8
The number 
is irrational, which means those y values in the table are irrational as well. So there's no way to get exact fractions for any of the decimal values.
The next best thing is to get approximate fractions.
A number like 4.1548 is the same as 
Then we can say:
Optionally we can reduce that if you wanted.
So the fraction 41548/10000 turns into the decimal 4.1548
The other decimal values are handled in a similar fashion.
I'm not sure why your teacher wants you to work with fractions. It's better if somehow you can type in the coordinate values as they appear in decimal form.
