Solve the problem.
the price of a printer was reduced from $400 to $300. what was the percent decrease?
30%
33.3%
25%
75%

25%.

Step-by-step explanation:

We are going to do a rule of three:

x= 75%.

Then, the percent decrease was 25%.

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
