Using the distance formula,


Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.
Formula for compound interest is
Interest = Amount - Principal
Interest =
- P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest =
- 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest =
- 400
So pair of equations for Jaina and Tomas are
Interest =
- 300
Interest =
- 400
Answer:
a. $3,333.33
b. $223,333.31
Step-by-step explanation:
a. $50,000 value increase and difference of 15 years 50,000/15 = 3,333.333333= 3333.33
b. difference 2006 and 1999 is 7 years, growth by year is $3333.33 so 3333.33 * 7 = 23,333.31 is difference in growth in those 7 years plus the original value of 1999 is $223,333.31
