Yolanda (y) read five more books than Richard (d), and Richard read two more books than Ronnie (r). Which equations express this mathematically?
A) y = 5d; y = 7r
B) y = d + 5; y = r + 7
C) y = d - 5; y = r - 7
D) y = d 5 ; y = r 7
Your answer is B. She read 5 more than Richard, so D + 5. & since Ronnie read 2 more than Richard, that’d be 5+2 = 7 to show how much more he read than Yolanda!
