makkiz [27]
If x and y are the acres under Tangerine trees and grapefruit trees respectively, then:

Total pounds of trees = 50x + 75y

For x = 25 acres and y = 15 acres
Total weight of trees = 50*25 + 75*15 = 2,375 pounds

This exceeds the maximum weight of fruits (that is, 1,500 pounds) possible from this farm. Therefore, John cannot have 25 acres of Tangerine trees and 15 acres of grapefruit trees.

Lunna [17]

Let pages written by Tom for a school report = x

Pages written by Jen for school report= 10 x

Pages written by Tom + Pages written by Jen = 396

→ x  + 10 x = 396

→ 11 x =396

Dividing both sides by 11, we get

→ x =36,

Pages wrote by Tom= 36 pages

Pages wrote by Jen = 36 × 10=360 pages
