Answer:
The coefficient, 5,000, best describes Suzanne's initial earnings.
Step-by-step explanation:
5000 represents the initial amount
here the initial earnings
Whenever amount earned is increasing compoundly we write
if rate of increasse is r% and t = no of weeks
Earnings at end of t weeks =
for all t = 1,2,3....
Thus 5000 appears as a coefficient for all t's
5000 is nothing but the initial earnings

Option 2.
1. Simplify 7 + (12 - 9) + 7 × 3(8 - 5)
According to the Order of Operations, contents of parentheses are evaluated first. This gives
... 7 + 3 + 7 × 3 × 3
Then multiplication and division are performed left to right.
... = 7 + 3 + 21 × 3
... = 7 + 3 + 63
Followed by addition and subtraction left to right.
... = 10 + 63
... = 73
A Google search box can be relied upon to do the operations in the correct order.
_____
2. When the expression is rewritten, a different result is obtained. This is because the operations indicated by the second set of parentheses are altered.
... (7 + 12) - 9 + (7 × 3)8 - 5
... = 19 - 9 + 21 × 8 - 5
... = 19 - 9 + 168 - 5
... = 10 + 168 - 5
... = 178 - 5
... = 173
In the first expression, both +8 and -5 are multiplied by 21. In the rewritten expression, only +8 is multiplied by 21.
