In a basket of apples, 12% of them are rotten and 66 are in good condition. find the total number of apples in the basket. make it understandable.

Explanation:

12% of the apples are rotten so 88% are in good condition (note how 12% + 88% = 100%)

Let's say that x is the amount of total apples. Taking 88% of x will get us 66 as there are 66 good apples, so,

0.88*x = 66

To figure out x, we divide both sides by 0.88 which undoes the multiplication

0.88x = 66

0.88x/0.88 = 66/0.88

x = 66/0.88

x = 75

There are 75 total apples. We can check this by taking 88% of this to get

0.88*x = 0.88*75 = 66

and we get 66 apples as expected.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
