Step-by-step explanation:

R = report length

R = 40 + (3/8) R + (1/3) R

3/8 = 3*3/8*3 = 9/24

1/3 = 8*1 / 3*8 = 8/34

R = 40 + (9/24) R + (8/24) R

R = 40 + (17/24) R Subtract 17/24 from the left

R-17/24 R = 40

7/24 R = 40 Multiply both sides by 24

7R = 40 * 24

7R = 960 Divide by 7

R = 960/7

R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138
