_________________________
Step-by-step explanation:
______________________________________________
Given: Eighty ("80") less than 4 (four) TIMES (a number);
______________________________________________
Looking at the answer choices given, we find the variable, "x", in each answer choice given.
_________________
So, "Given: Eighty ("80") less than 4 (four) TIMES (a number);" ;
___________________________
We shall let "a number" be represented by the variable, "x"
____________________________________________
Now, 4 (four) TIMES that number, = 4 * x ; or, write as: "4x"
______________________________________________
Now, Eighty (80) LESS THAN (4x) would be 4x MINUS 80 ; or,
_______________________________________________
4x − 80 ; which is: Answer choice: [A].
