Pauline withdrew $7.50 from her savings account every day for 3 days. Which expression is the best choice to help her determine

artcher [175]

Answer:

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

Step-by-step 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 = $(Money\ withdrew\ each\ day)\times (number\ of\ day)$

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

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
