Open bracket



Answer:
the answer to your question is 22/25 , hope this helps :)
year 1
cost = 1.03 (1500) = 1545
put 1545 in for x in year 2
year 2
1.03 * 1545 = 1591.35
put in 1591.35 in for x in year 3
year 3
1.03 *1591.35=1639.0905
round to the nearest cent
cost in three years: $1639.09
Choice C
Answer: 40 %
Step-by-step explanation:
Let the amount of one card = x
Hence, the value of 20 cards ( Principal amount ) = 20x
And, the value of 22 cards ( Total amount after 3 month ) = 22x
⇒ Total interest in 3 month = 22x - 20x =2x
Let the annual interest rate = r %
( By the formula of simple interest rate )




Hence, the annual rate of interest = 40%
1. The diagonal is the hypotenuse so,
√[12² + 12²] = 16.97
2. The same process is done
51.96
3. Again, use the Pythagorean theorem
35.78
4. The perimeter is 44, so the length of a side is 11, the diagonal is
15.57
5. The diagonal is 20, the formula is
d =s√2
where d is the diagonal and s is the side
s = 14.14
