Final value = Initial value × (mutiplier)^n
We have;
Initial value = 9300
Multiplier = 100%+3.2% = 103.2% = 1.032
Number of quarters in a year = 4
Substitute all values into the formula, we have
rounded to two dp
Answer:
B) retirement
Step-by-step explanation:
Retirement is the only one that makes sense to me when you regularly save a small amount of money, and then letting the value grow over time.
Hope this helps!!
Answer:
1 / 2 or 0.5
Step-by-step explanation:
use the formula ; m = y2 - y1 / x2 - x1
where y2 = 10
y1 = 9
x2 = 5
x1 = 3
To solve this, set up a proportion where X is the amount that 120 lawn mowers would cost. It would look like
.
Then cross-multiply to get 40x = 120(4776) or 40x = 573120. Now divide each side by 40 to isolate the variable.
X = 14328.
120 lawn mowers would cost $14,328.
The sequence would be written as:
1.2, 0.84, 0.588, 0.4116
If this is a geometric sequence, then they should have a common ratio. We determine as follows:
0.4116 / 0.588 = 0.7
0.588 / 0.84 = 0.7
0.84 / 1.2 = 0.7
r = 0.7
an = a1(r^(n-1))
an = 1.2 (0.7^(5-1))
an = 0.28812 <--------option A
