Use an equation for questions like these:
I'll use x and y as the unknown numbers
x-y=0.7
x+y=1
Just choose either x or y to solve for
y=x-0.7
y=-x+1
Then since since they're both equal to y then they can equal each other
x-0.7=-x+1
2x-0.7=1
2x=1.7
x=0.85
Then just grab one of the equations and use it to find y
0.85+y=1
y=0.15

So the two numbers are 0.85 and 0.15

The two numbers are 0.85 and 0.15
if you add them together you get 1, 0.85+0.15=1
and if you subtract them you get 0.7, 0.85-0.15=0.7

An investment made in the stock market decreased at a rate of 1.2% per year for 25 years. What is the current value of the $100,
densk [106]

Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have


A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.


The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.


Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.

Anvisha [2.4K]

Answer:

Answer choice A(57%)

Step-by-step explanation:

The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)
