A number y times fives is at most one hundred

20

Step-by-step explanation:

twenty times five is one hundred, so, I hope that's the answer you're looking for

y <= 20

Step-by-step explanation:

Since it says a number y, our variable is y.

The number is multiplied by 5 which gives us 5y.

It is at most one hundred which means this is an inequality. It is AT MOST which means that 100 is a possible value. This means that our inequality is:

5y <= 100

Now we divide both sides by 5 to isolate y

y <= 20

25% is the answer
