Answer:
B
Step-by-step explanation:
b is correct
Before her promotion, Mitch was receiving $40,000 per year
after tax. Since the loan payment is 4%, therefore the money that goes to the
loan is:
Loan payment = $40,000 * 0.04
Loan payment = $1,600
After her promotion, Mitch is now receiving:
New salary = $40,000
* 1.25
New salary = $50,000
Therefore the new loan payment becomes:
New loan payment = $50,000 * 0.04
New loan payment = $2,000
Therefore Mitch is paying an extra payment of:
$2,000 - $1,600 = $400
Answer: $400
Bring the 3 to the other side, which makes 11-3 = 8
divide the whole equation by 2, which makes it Root (3x/5) = 8/2
square the whole equation which gives
, 3x/5 = 16
Multiply the equation by 5 which makes it, 3x = 80
finally divide the equation to find x, x= 80/3
account b has 2.6% more interest than account a
