Answer:
The extra amount to be paid = $ 309.15
Step-by-step explanation:
Credit card bill = $ 7250 .
Interest rate = 16 % .
<h3>
AMOUNT TO BE PAID IN 1 YEAR</h3>
Monthly payment = $ 657.80
Total amount to be paid in a year = $ 657.80 × 12 = $ 7893.6
Interest amount in 1 year = $ 7893.6 - $ 7250 = $ 643.6.
<h3>AMOUNT TO BE PAID IN 18 MONTHS </h3>
Monthly payment = $ 455.71.
Total amount to be paid in a 18 months = $ 455.71 × 18 = $ 8202.78
Interest amount to be paid in 18 months = $ 952.78 .
The extra amount to be paid = $ 8202.78 - $ 7893.6 = $ 309.15
Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅
Check the picture below.
make sure your calculator is in Degree mode.
The answer is equation 2. The reasoning is because a linear function is y=mx+b
therefore, y=8x+1 seems to be very close.
