Jane paid $40 an item after she recieved a 20% discount. jane's friend says this means that the original price of the item was $48. how do you think jane's freind arrived at this amount? is her friend correct? why or why not?

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
