Christine has $500 to deposit in a savings account, and she is trying to decide between two banks. bank a offers 10% annual interest compounded quarterly.
rather than compounding interest for smaller accounts, bank b offers to add $15 quarterly to any account with a balance of less than $1,000 for every quarter, as long as t
here are no withdrawals. christine has decided that she will neither withdraw, nor make a deposit for a number of years. develop a model that will christine decide which bank to use.

Christine should make a annual model adequated to her needs.

Step-by-step explanation:

-First, she should save those $500 until she gets to the $1000.

-Then depending on the number she gets use these formulations:

For bank A: (x)*.10

For bank B: (x*.15)15

x= the total number of savings that Christine has at the end.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
