Directions: Select ALL the correct answers.

Brandon goes to an ATM near his house and withdraws x dollars from his checking account. Since the ATM is not at the same bank where his checking account is, the bank charges a $2 fee for each transaction, which is withdrawn from his account in addition to the x dollars.

Brandon makes this same withdrawal at this same bank once a week for seven weeks. Which of the following expressions could represent the total amount withdrawn from Brandon's checking account during this time period from these ATM transactions?

7x + 2
7x + 14
7(x + 2)
7x + 9
(7)(x) + (7)(2x)
(7)(x) + (7)(2)

Answer 1

7(x+2)

Explanation:

so he withdraws x dollars

he doesn't use his home bank so the bank withdraws 2 dollars for itself

so each time he withdraws x+2 dollars

he does it 7 times so he withdraws 7(x+2)

so the correct choices are equal to this so

so 7(x+2) distribute

distributive property=a(b+c)=ab+ac so

7(x+2)=(7)(x)+(7)(2)

and if we multiply that out we get

7x+14

the answers are

7(x+2)

Answer 2

so he withdraws x dollars
he doesn't use his home bank so the bank withdraws 2 dollars for itself
so each time he withdraws x+2 dollars

he does it 7 times so he withdraws 7(x+2)
so the correct choices are equal to this so
so 7(x+2) distribute
distributive property=a(b+c)=ab+ac so
7(x+2)=(7)(x)+(7)(2)
and if we multiply that out we get
7x+14

the answers are
7(x+2)
7x+14
(7)(x)+(7)(2)
