Answer:

3B = R

R/3 = B

S + 50 = R

S = R - 50

R + S + B = 972

(R - 50) + (R/3) + R = 972

2R - 50 + R/3 = 972

7R/3 - 50 = 972

7R/3 = 1022

7R = 3066

R = 438

B = R/3

B = 438 / 3

B = 146

S = R - 50

S = 438 - 50

S = 388

S - B

388 - 146 = 242

Answer: Sapphire has 242 more dog biscuits than Briggs.

Explanation:

R = Roxy

B = Briggs

S = Sapphire

First, set up what you know from the problem.

Now, you need to find Sapphire and Briggs. Display all of them in terms of R. Then, add all the values together, algebraically.

Hope this helps!
