Demetrius deposits $120 iinto his account. One week later he withdraws $36. Write an addition sentence to represent this situati

Zolol [24]

Answer:

Demetrius's account is $84 higher after the two transactions

Step-by-step explanation:

Let

x -----> original amount in Demetrius's account

y ----> amount in Demetrius's account after the deposit and the withdraws

we know that

The amount in Demetrius's account after the two transactions must be equal to the original amount in Demetrius's account plus the deposit minus the withdraws

$y=x+120-36$

$y=x+\$84$

therefore

Demetrius's account is $84 higher after the two transactions
