So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
In the above word problem, If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles, Quarter 8-inch tiles will cover the same area as one 2-inches.
<h3>What is the justification for the above?</h3>
Note that the area of the one 2-inch tiles is given as:
A1 = 4in²
The area of the quarter 8-inch tiles is:
A2 = 1/4 x 8 x 8
A2 = 16inch²
Divide both areas
A2/A1= 16/4
= 4
This implies she'll need four 2-inch tiles to cover the same amount of space as a quarter 8-inch tile.

<span>The question said that Juan earns 5 percent on the first ten suits sold. Commission earned on the first ten 250.00 dollars suits = 5% of 250.00 times 10 suits = 0.05 x 250 x 10 = $125.00. The question said that he earns an additional 3 percent on additional suits exceeding 10 suits making a total of 8 percent. Since Juan sold 13 suits, he sold 3 additional suits. 8% of 250.00 times 3 suits = 0.08 x 250 x 3 = $60. Therefore, total commision = $125 + $60 = $185.00</span>
