Roseanna did not pay last month's credit card bill in full. her daily balances for her last billing cycle are listed. what was roseanna's average daily balance to the nearest cent? (hint: find the average or mean of these numbers.)

for seven days she owed $456.11

for three days, she owed $1,077.00

for six days, she owed $900.08

for nine days, she owed $2,113.15

for five days, she owed $2,310.15

$228.54

Step-by-step explanation:

Given : Roseanna did not pay last month's credit card bill in full. Her daily balances for her last billing cycle are listed.

To Find: What was Roseanna's average daily balance to the nearest cent?

Solution:

For seven days she owed $456.11

For three days, she owed $1,077.00

For six days, she owed $900.08

For nine days, she owed $2,113.15

For five days, she owed $2,310.15

Mean =

Mean =

Mean =

Mean =

Hence Roseanna's average daily balance to the nearest cent is $228.54

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
