Clay has 6 times as much as Julian. Troy has twice as much money as Julian. Altogether, they have $45. How much money does Clay have?

Question

A. 12

B. 28

C. 30

D. 38

Answer 1

Looks like the "reference" person is Julian.
Let Julians' amount be x
then Clay has 6x
and Troy has 2x

x + 6x + 2x = 45

A piece of cake from here on.

Answer 2

6 * 2 = 12

6 * 3 = 18

18 + 12 = 30

Answer 3

6 + 3 = 9

45 / 9 = 5

6 * 5 = 30
