At the supermarket Pryslide, 500ml bottles of shower gel cost $7 each. However, since the beginning of last week there has been

max2010maxim [7]

Answer:

I strongly believe that the question requires us to calculate the cost of one 500ml bottle of shower gel based on this special offer of buy 2 bottles get another for just $2.

The correct answer is $5.33

Step-by-step explanation:

From a buyer's point of view,a 500ml bottle of shower gel cost is the $7 multiplied by 2 bottles plus $2 multiplied by 1 bottle all divided by 3 bottles.

The rationale for the denominator is that the total number of bottles bought would then equal 3 bottles .

Cost per bottle =($7*2)+($2*1)/3=$16/3=$5.33

Instead of a bottle costing $7,under the special arrangement a bottle would simply cost $5.33

What is the slope of the line that passes through the pair of points (-2,7) (18,1)

dusya [7]

Your points are (-2, 7) and (18, 1). To find the slope, use the slope formula (y_2 - y_1)/(x_2 - x_1)
(18, 1) --> (x_2, y_2)
(-2, 7) --> (x_1, y_1)
(1 - 7)/(18 - (-2)) --> -6/20 --> -3/10
The slope of the line passing through the points (-2, 7) and (18, 1) is -3/10.
