The inequality will be x ≤ 14.28 and Mr. Valentino can purchase a maximum of 14 packs of paper.
What is inequality?
A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's say there is x pack of paper.
Cost of x pack of paper 1.75x
Now Mr. Valentino has only $25
So,
1.75x ≤ 25 ⇒ x ≤ 14.28
It means Mr. Valentino can purchase 14 packs of paper.
