15%

Step-by-step explanation:

1. Subtract the sale price from the normal price.

$1000 - $850 = $150.

2. Divide this amount by the original price.

$150/$1000 = 0.15

3. Multiply by 100 to get the %.

0.15 x 100 = 15%

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
