Answer: Sample is biased
Step-by-step explanation:
In her experiment, Gloria assumes that the reading habits of the students in her school district are exactly the same to that of students in all state schools. This assumption is unlikely to be true and, therefore, this statistic is misleading because the sample used is biased.

x + y = -22 ........(1)
x - y = 122 ........(2)
By adding equation 1 & 2-
2 x = 100
x = 50
Put X =50 in equation (1)-
y = -22 -50
y = -72
Hence the numbers are (50, -72).
A is correct because if you subsitute 5 for d or days, you get 140 for both equations
