The digit 5 is usually rounded up, but it can also be rounded down. How would you round the numbers in the equation 9.5 + 4.7 + 3.2 + 7.5 = x to the nearest whole number without getting an overestimate or an underestimate?​

I would round 5 up and anything below 5 would be rounded down.

10 + 4 + 3 + 8 = x

25 = x

Let me know if I explain this wrong but from what I understand, what you would do is 9m5 and 7.5 together ad .5 and .5 are 1. That means 9+1+7. Next is 4.7 and 3.2 The problem with this us that .7 and .2 are .9 however that is important. 4+3 is 7 and we know .9 so it's 7.9. now just add the whole numbers and 7.9 and then you get your perfect answer. this answer was mainly just distributive property. hope I helped

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
