Answer 2

`\$(-7.50)(3\ days)= - 22.50`

Explanation:

Given: Pauline withdrew $7.50 each day from her saving account.

She withdrew money for 3 days.

As Pauline is withdrawing the money, therefore the amount will be in negative

Now finding the expression for total amount of money withdrew.

Total money withdrew =
`(Money\ withdrew\ each\ day)* (number\ of\ day)`

∴ Total money withdrew =
`\$ -7.50* 3\ days= - 22.50`

Hence, the expression to determine the total amount of money she withdrew is
`(-7.50)(3)= -22.5` and Total money she withdrew is -$22.5
