Once Emily's bank account fails below $0. her bank charges her $3 each day until
she makes a deposit to reach a positive
balance. If the balance in her account is
$32 and she makes a $60 purchase, what is
the balance in her account after 7 days if
she does not make a deposits

Explanation:

Her original balance starts off at $32. After making the $60 purchase, her balance becomes 32-60 = -28 dollars. We wouldn't say 60-32 = 28 because the expense is larger than her balance.

Being in the negative territory means Emily is in debt to the bank, until she can get her balance back to $0 or higher. Since they charge her $3 a day for being in the negative area, and her balance is like this for 7 days, then they charge a total of 7*3 = 21 dollars.

So the -28 will drop to -28-21 = -49 dollars

If she doesn't want any more charges done, she needs to deposit $49 or more into the account on the 8th day.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
