Vivian is doing word searches on her smartphone. Her highest score in the game is 42 points higher than her lowest score. If her highest score is 438, what is her lowest score? People enjoyed attending the concert in the park. Twice as many men as women attended the concert. If the total attendance was 714, how many women attended the concert? The length of a rectangular park is 3 feet shorter than times its width. If the length is 123 feet, what is the width of the park in feet? Darwin’s age is 6 years greater than twice Fiona’s age. If Darwin is 50 years old, how many years old is Fiona?

Vivian problem: If her highest score is 42 points higher than her lowest score, just subtract 42 from 438. The answer is 396.

Concert problem: let w=women and 2w=men. your equation would be: w+2w=714
3w=714
w=238. There were 238 women.

Park problem: let the length=3w and the width=w. so, to find w, you would have to divide by 3, and since the length is 123, do (your equation would be 3w=123) 123/3 which would give you 41 ft for the width. 

Darwin's age: let darwin's age=2f+6 and fiona=f. If darwin's age=50, then set 2f+6=50
2f=44
f=22. Fiona's age is 22 years.
