Answer:

the answer is c

Step-by-step explanation:

x and y have to be at least 12, so that's why the greater than sign was used

the amount of money had to be at most $230, so that's why the less than sign was used

they said x and y represent black and white respectively, so that means x is black and y is white, so it is 18x and 20y

I see the amount was $90.00 then reduced to $<br>75.00 , what is the percent ?
VashaNatasha [74]

Answer:

16 2/3 %

Step-by-step explanation:

Since the price went down, we are find the percent decrease.

Percent decrease = (original price - new price)/ original price

                               = (90 - 75)/90

                                =15/90

                                  .1666666666666

Changing to percent form

                                      16.6666666666666666666666%

                                       16 2/3 %
