Answer:
$14,080
Step-by-step explanation:
You can use a formula for exponential decay, but since it is only 2 years, you can find 80% of the original value, and then 80% of the new value.
Original value: $22,000
Value after 1 year: 80% of $22,000 = 0.8 * $22,000 = $17,600
Value after 1 year: $17,600
Value after 2 years: 80% of $17,600 = 0.8 * $17,600 = $14,080
Answer: $14,080
Answer:
l=20m
w=5m
Step-by-step explanation:
Let "l" be the length of the rectangle &
let "w" be the width of the rectangle
l=15+w
P=2(l+w)
50m=2(15m+w+w)
50m=2(15+2w)
50m=30m+4w
20m=4w
w=5m
l=15m+w
l=15m+5m
l=20m
Proof:
P=2(l+w)
P=2(15m+w+w)
50m=2(20m+5m)
50m=40m+10m
50m=50m
