Inequality is the comparison of mathematical expressions which are not strictly equal. The needed inequality is: 18.45 ≥ 3 + h
How to form mathematical expression from the given description?
You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For the given case, we've got:
Amount spent by Leticia = $18.45
Amount spent by Humberto = h dollars
Since amount spent by Leticia is at least $3. 00 more than what Humberto spends, thus:
18.45 is at least h + 3 (all in dollars)
(we usually skip stuffs like currency sign or units in equations or inequalities, to keep things as minimized as possible. It is known from the context what unit or currency or such thing is being discussed).
At least can be thought of as equal to that quantity or greater than that quantity but not less than that quantity.
This more than or equal to is written as ≥
Thus, the inequality we get is:
18.45 ≥ 3 + h
