 4.Here is the formula given Girls W= 1/4x + 159. Boys W= -x + 140.W is the average writing score X years after 1998.
1.If current trends continue, when will the average test score for girls be 49 points higher than for boys? 
2.If the current trends continue, when will the average test score for girls be 54 points higher than for boys?
They printed the answer for #1 as the year 2022 Girls W= (1/4)x + 159. Boys W= -x + 140.W is the average writing score X years after 1998.
1.If current trends continue, when will the average test score for girls be 49 points higher than for boys?

Equation:
Girls = Boys + 49
(1/4)x+159 = -x+140 + 49
(5/4)x = 30
(1/4)x = 6
x = 24

Year: 1998+24 = 2022
