Question

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situation. How much higher or lower is the amount in his account after these two transactions?

Answer 1

`Expression = x + 150 +(- 26)`

$124 higher

Explanation:

Given

`Deposit = \$150`

`Withdrawal = \$26`

Required

Represent the situation

Determine how much higher or lower is the remaining amount

Let the initial amount in his account be represented with x

When he deposited, the balance becomes

`Balance = x + 150`

When he withdrew, the balance becomes

`Balance = x + 150 + (-26)`

Hence, the algebraic expression is

`Expression = x + 150 +(- 26)`

Calculating how much higher or lower

`Balance = x + 150 + (-26)`

Open bracket

`Balance = x + 150 -26`

`Balance = x + 124`

Recall that the initial amount in the account is x

The difference between the balance and the x is as follows

`Difference = x + 124 - x`

`Difference = \$124`

Hence, the account has a higher of $124 after both transactions
