Answer 1

To find the remaining amount on a gift card after 6 uses, the equation y = -20x + 200 is used, substituting x with 6, resulting in y = 80 dollars remaining.

Step-by-step explanation:

The student is asking about the amount remaining on a gift card after a certain number of uses, which is represented by the equation y = -20x + 200. To find the amount remaining after 6 uses, we simply substitute x with 6 and solve the equation:

y = -20(6) + 200
y = -120 + 200
y = 80

Therefore, the amount remaining on the card after 6 uses is $80, which corresponds to option B.
