Ultrasounds use sound waves to create images in real time. Therefore, medical doctors can use these to observe internal organs <em>and </em>blood vessels.
Let x and y be the price of the fridge and the freezer before the sale, respectively.
Since the sale offers 15% off everything, Kristianne actually paid the remaining 85%
We are given that the freezer costed 250 before the sale, i.e. y=250. Plug this value in the equation to get
We can manipulate this expression to get
The amount of interest saved by the borrower is $62.61
Step-by-step explanation:
1. To calculate rate of 36 monthly payments,
Principal = $4200
Rate = r%
Time = = 3 years
Interest = $141.17
Formula for calculating interest is,
Interest =
141.17 =
141.17 x 100 = 12,600 x r
r =
r = 1.12%
2. To calculate interest of 20 monthly payments,
Principal = $4200
Rate = 1.12%
Time = = 1.67
Interest = I
Formula of interest --> I =
I =
I =
I = $78.56
3. Amount of Interest saved = Interest of 36 monthly payments - Interest of 2- monthly payments
Interest saved = 141.17 - 78.56
Interest saved = $ 62.61
Therefore, the amount of interest saved is $62.61
