Roxan is 74,820. How many marbles does Roxan have? Give your answer to two
decimal places.

Answer 1

Answer:

18,570

Step-by-step explanation:

Let T,B,R,P denote the number of marbles held by Tallula, Bob, Roxan and Pauline respectively.

We are given that

T = 2R

B = R

P = 0

T + B + R = 74,820

2R + R + R = 74,280

4R = 74,280

R = 18,570
