Answer:
Bob Saves 168$.
Step-by-step explanation:
According to the Question,
- Given That, Amy , bob and hadi saved $1012 altogether.
Thus, A + B + H = 1012 ⇒ Amy saved $85.
So, B + H = 927 ----- Equation 1
- And Hadi saved 3 times as much as the total amount of Amy's and Bob's savings So, H = 3(A + B) ⇒ We Know Amy saved $85.
So, H - 3B = 255 ----- Equation 2
- Now, Subtract Equation 2 from Equation 1, We get
4B = 672 ⇒ B = 168
Bob Saves 168$.
