First distribute the negative over the parentheses:-
= 7s^2 + 3s - 4s^2 + 3s - 1
= 3s^2 +6s - 1
Answer:
<u>Calvin withdraws $ 60 each week</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Calvin's account balance difference than 8 weeks ago = - $ 360
Weekly amount Calvin deposits = $ 15
Number of weeks to compare = 8
2. What was his average withdrawal each week?
Let's calculate the weekly average withdrawal this way:
Weekly average withdrawal = [Calvin's account balance difference than 8 weeks ago - (Weekly amount Calvin deposits * Number of weeks to compare)]/Number of weeks to compare
Replacing with the values given:
Weekly average withdrawal = [-360 - (15 * 8)]/8
Weekly average withdrawal = -360 - 120 / 8
Weekly average withdrawal = -480 / 8
<u>Weekly average withdrawal = -60</u>
<u>Calvin withdraws $ 60 each week</u>
