Question

John opens a savings account with an initial deposit of $2000. He deposits 535 each week. Mary's savings account is represented by the function y =545x + $2800, where y is the balance of Mary's savings account after her initial deposit and a number of weekly deposits, x Which statement BEST compares the rate of change for the two accounts? A) Mary deposited 800 less than John 3) John deposits 10 more each week than Mary. John deposits 10 less each week than Mary. Dj Mary deposits 7 for every 9 John deposits.

Answer 1

First, we need to find an equation that represents John's savings.

Now, the initial deposit of $2000 is the independent value and $535 each week represents the dependent value.

Let's set x for the number of weeks. Therefore, we can write the next equation:

$y=535x+2000$

and Mary's savings account is represented by the function:

$y=545x+2800$

We need to compare both equations:
