Answer:
25 decreased by 30% equals 17.5
Step-by-step explanation:
To solve this, we need to make our equation to solve.
x/25=30/100
We did x because we don't know what 30% of x is. The 25 shows the total, while the right side shows the percent.
Now cross multiply
100x=750
Now divide both sides by 100.
you will get x=7.5
So now we know that 7.5 is 30% of 25. Now, subtract 7.5 from 25 in order to find out what 25 decreased by 30% is.
25-7.5=17.5
So the answer is 17.5
