What value of r makes the equation true? r 0.12 = 0.20 A. r = 0.32 B. r = 0.08 C. r = –0.08 D. r = –0.32
muminat
Depends on your question...

If your question is r + 0.12 = 0.20 then do this:

Subtract 0.12 from both sides

r = 0.08

The answer is B.


If your question is r - 0.12 = 0.20 then do this:

Add 0.12 on both sides

r = 0.32

The answer is A

So it depends on your question :P

At River Bank, checking account customers earn 0.75% interest a month on their account balances, pay no service fees for writing
vlada-n [284]

Solution:

1. Account balance of customer=  $ 1,000

Interest earned in checking account= 0.75%

Financial charge= $ 2

So, income earned in one month on the checking account

= 0.75% of 1,000 - $ 2

=\frac{0.75}{1,00\times 100}\times 1,000 -2\\\\=7.50-2\\\\=5.50

Option (B) $ 5.50

2. Checking account earnings at Baker’s Bank  (I) = -0.09 x + 10.2

    The earnings at Elite Bank are modeled by: I = -0.02 x + 7.5

The number of checks when Elite Bank start generating more checking account income than Baker's Bank is given by inequality,

→→ -0.02 x +7.5 > -0.09 x +10.2

→→ -0.02 x + 0.09 x > 10.2 - 7.5

→→0.07 x > 2.7

→→x>\frac{2.7}{0.07}\\\\ x>\frac{270}{7}\\\\ x>38 \frac{2}{7}

So, the number of checks should be a whole number.

So, when number of checks = 39,→→Option (C) Elite Bank will start generating more checking account income than Baker's Bank.

3. Total amount in Emilio's checking account at the end of the week=( Beginning Balance= $ 728.32) -[4 Checks=( 99.48 +33.50 +18.23 +72.05)]+ $ 1109.90(Paycheck amount)

= 1109.90 + 728.32 - 223.26

= $1614.96 →→ Option (D)
