Answer:
$122.88
Step-by-step explanation:
the phone decreases by 20% each year , that is
(100 - 20)% = 80% =
= 0.8
the phone reduces by a factor of 0.8 each year , then after 4 years
value = $300 ×
= $122.88
Answer:
56 decreases to 11 because 45 was subtracted from it.
56-45=11
Q + d = 100 so q = 100 - d
0.25q + 0.10d = 19
substitute q = 100 - d into 0.25q + 0.10d = 19
0.25q + 0.10d = 19
0.25(100 - d) + 0.10d = 19
25 - 0.25d + 0.10d = 19
-0.15d = -6
d = 40
q = 100 - 40 = 60
