At the start of the week, monique’s savings account had a balance of $326. she made a $45 withdrawal each day for seven days. during that week, she also made two deposits of $125 each. which integer represents the balance in monique’s account at the end of the week?
–891
–261
261
891

What i did first is 326 plus 125 times two 
326+125+125=567 
then subtract 567 from 45 times 7 
567- 45x7 =261 < that's your answer 

Positive 261 is correct. 45•7= 315
326+250= 576
576-315= 261

1. the total cost is $25.02

You have to add all the cost of the family had which is $6.84+$4.88+$8.32+$4.98

2.they would get $13.73 back

I got it by the $25.02 from the last one and add with tax which was 5% so I then in total of $26.271 and since this is money I rounded it up to $26.27. After I got that I subtracted the $40 since they use 2 $20. $40-$26.27=$13.73

3. I think it would be the estimate of 0.60 per ounce

I got that by dividing the total cost and the all the ounces which I got the estimate of 0.60

4. I think they should order the larger steaks than the smaller steaks to share since it would be for one family.

I am sorry if one of them are wrong but I hope this could help you.
