c) (ii) after 19 years, ada = (x+ 19) and bill = ( y + 19).

or, y = 2x + 19

(b) Matthew made a bookcase.
The cost of making the bookcase was $647.50.
After the bookcase is sold and the shopkeeper has received 15% of the selling price,
Matthew makes a profit of $160.
Calculate the selling price of the bookcase.

Matthews receives = 647.5 + 160 = $807.5
Now, since the shop keeper receives 15% of the selling price, Matthew receives 85% of the selling price.
So,
807.5 = 85/100 * x (where x = selling price)
Calculating x,
x = $950.

Bro add maths comp

 

[sourov97]

The cost of making this table was $131.80.
Matthew keeps 85% of the selling price!..so he receives = (85/100) * 200 = $170
so percentage profit = [(170/131.8) * 100%] - 100 = 28.9 = 30%

Bro add maths comp

Before Chemistry, I was thinking to get it in Chemistry. I came close.
Before Physics, I was thinking to get it in Physics. Not even close.
Before Maths, I was thinking to get it in Maths, I have come perilously close.
Now, I'm just hoping on Add.maths, not computer.

Yes but it also requires almost 100% and I almost always lose at least 3-5 marks in theory papers.
