Suppose you can get a higher interest rate on your savings if you maintain a balance of at least $1000 in your savings account. the balance of your account is now $1058. you deposit $44.50 into your account. what is the greatest amount that you can withdraw and still get the higher interest rate?

$102.5

Step-by-step explanation:

∵ The balance of the account = $ 1058,

After depositing $ 44.50 in the account,

Balance of the account = 1058 + 44.50 = $ 1102.5,

Let x be the amount ( in dollars ),

Which is withdrawn from the account,

So, the final balance of the account  = (1102.5-x) dollars

∵ For getting higher interest rate,

Balance ≥ $ 1000,

⇒ 1102.5-x ≥ 1000

⇒ 1102.5 ≥ 1000 + x

⇒ 1102.5 - 1000 ≥ x

⇒ 102.5  ≥ x

Hence, the greatest amount that can withdraw would be $102.5

b = 0.8 or 4/5

Step-by-step explanation:

3/5 = b + (-1/5)

0.6 = b + (-0.2)

0.6 = b - 0.2

0.6 + 0.2 = b

0.8 = b

b = 0.8 or 4/5
