dai is comparing how many trading cards he has with his friend maura. initially they find that dai has four more cards than twice the number maura has

B)

Step-by-step explanation:

The question states that Dai has 4 more cards than twice the number of cards Maura has.

"more" - add

"twice" - multiply by 2

Let n be equal to the number of cards that Maura has.

Let D be equal to the number of cards that Dai has.

When we translate this into an equation, we would get something that looks like...

Since Dai has four more cards than twice the number of cards Maura has, 2 times the number of cards Maura has plus four is equal to the number of cards Dai has. Hopefully this is easier to understand written like an equation!

Therefore, the expression would be .

I hope this helps!
