</span>
<span>c. Mary's total cost
$250 + $3598 = $3848

Slope = y2 - y1/x2 - x1
6 - -3/1 - -6
=9/7
So here you are trying to find out what times .30 (30%) subtracted the original price will give you 18.75. Because it is 30% discount you want to use 70% (.7) so that you can find the price before not the price after.
so .7(x) = 18.75
Which you then divide and then get 26.79 dollars.
The side opposite to angle B is the side that does not contact with angle B.
In this attached image, you can see better that sides AB and BC is in contact with angle B. So, the opposite side to angle B is AC.
Therefore, the lenght of the side opposite to angle B is 4 units.
1 ft = 12 inches....so 10 ft = (10 * 12) = 120 inches
each strip of wall paper is 20 inches...
so 120/20 = 6 strips of wall paper are required <==
