A teacher writes on the board:"Elijah has 3 times as many coins as Tom, and mark has twice as mainly coins as Elijah. Then she asks, mark has how many times as many as Tom

Mark has 6 times as many as Tom

Step-by-step explanation:

Elijah = E

Tom = T

Mark = M

Translate the information into mathematical equation:

E = 3T

M = 2E

How many times Mark has as many as Tom?

M = ... T?

M = 2 E (Remember, E = 3T, insert this)

M = 2 (3 T)

M = 6 T

Mark has 6 times as many as Tom
