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.
Step-by-step 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!
