Answer:

2x+15=33

Step-by-step explanation:

Let n be the number of days he has been doing sit ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2n.

Since he started doing 15 sit-ups on the first day, the total number of sit-ups

after x days would be 2n+15.

Since he did a total of 33 sit ups today, then 2n+15=33

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
