The difference y less than 10

The difference is : 10 - y

Step-by-step explanation:

Let we donate the required difference by 'd'

Now, we need to find difference(d) in such a way that it is y units less than 10. So, Using concept of algebraic expressions :

A number which is less than another can be found by subtracting first number from the second number :

So, the required difference is given by : d = 10 - y

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
