Answer:
Step-by-step explanation:
If x varies directly as the product of p and m, and inversely with y, the relation can be written ...
x = k(pm)/y . . . . where k is the constant of proportionality
__
This can be solved for k:
k = xy/pm
For the given values, the value of k is ...
k = (2)(4)/((0.5)(2)) = 8
Then the relation between the variables can be written ...
(xy)/(pm) = 8
I think your answer will be A. Aleta can buy 10 tops if she only buys 2 pair of pants.
for 10(15)+2(30)=$210
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
