The rate of change in the account for a week is $157.5.
Annalise has some money in her bank account. She withdraws $22.50 per day from her account for a week. We need to represent the change in the account for the week. The number of days in a week is seven. So, it means that she withdraws money from her bank account daily for seven days. The total amount of money withdrawn from the bank account is the product of the withdrawal amount per day and the total number of days in a week.
A = $22.5*7 = $157.5
Let the initial amount of money in the bank be "$x". The change in the bank balance is $157.5. The current balance is $(x - 157.5).

Answer:
320in²
Step-by-step explanation:
Labelled diagram shown above.
Surface area : base × height
The surface area of most of the sides will be the same because the sides are the same.
Top/bottom = 5 × 8 = 40 + 40 = 80in²
Side/Side = 5 × 10 = 50 + 50 = 100in²
Front/Back = 8 × 10 = 80 + 80 = 160in²
Add them all together.
160 + 100 + 80 = 340in²
