1/10.
2/5 is equal to 4/10
4/10 divided by .4 is .1
so its 1/10
Hi there,
The equation to this is going to be : c = 3r - 3s
If you want to get the lower price down you are going to have to buy 3 shampoo bottles in order to get a lower price. The cost you save is the main difference from a regular price. And the answer is c = 3r - 3s
Well you are trying to find x, so you would divide 5/8 by itself and on the other side.
(5/8x / 5/8) = (10 / 5/8)
x=16
Hope this helps!
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ), b = 75
The formula is: y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.
