Question
Translate the following phrase into inequality: Tom can spend no more than 20 dollars on his mom's birthday present.
- t > 20
- t < 20
- t ≤ 20
- t ≥ 20
Hint:
A mathematical representation of relationship between 2 or more variables or a variable and a constant wherein the relationship is not equal. i.e. greater than/ greater than or equal to/ less than/ less than or equal to. is known as inequality.
The correct answer is: t ≤ 20
GIVEN-
Amount that Tom can spend on his mom's birthday present should not be more than 20 dollars.
TO FIND-
Inequality that represents the given situation.
SOLUTION-
Let the Amount that Tom can spend be t.
From the given information, we get-
Tom can spend not more than $ 20 on his mom's birthday present. i.e. he can spend either $ 20 or less.
∴ Amount that Tom can spend <= $ 20
∴ t <= 20
FINAL ANSWER-
Option 'd' i.e. 't <= 20' is the correct answer to the given question.
