Dr. Sojo’s first-period class had 54 fewer extra points than her second-period class. Together they had 438 total extra points. How many extra points did each class have?

Sagot :

Second class extra points = x

First class extra points = x - 54

Both have 438 total extra points

x + (x-54) = 438

Solve for x

x +x - 54 = 438

x + x = 438 +54

2x = 492

x= 492/2

x= 246

First class = x -54 = 246 - 54 = 192 extra points

Second class = x = 246 extra points
