To find this, you just need to plug it in and use some algebra to figure it out.
Initial: 2700 = 2200(1 + r)5
multiply 2200 and 5: 2700 = 11000(1 + r)
Divide both sides by 11000: .24 = 1 + r
subtract both sides by 1: -.754 = r
The problem is, a negative interest rate makes no sense if there was actually an increase of 500. We can try distributing the 11000 instead
Where we left off: 2700 = 11000(1 + r)
Distribute the 11000: 2700 = 11000 + 11000r
Subtract 11000 from both sides: -8300 = 11000r
Divide both sides by 11000: -.754 = r
As you can see, both methods reached the same impossible answer. I'm assuming that you didn't type out the equation right. Are you sure it wasn't
2700 = 2200(1 - r)5
? If you subtract the r to make it negative, it might make more sense. But that still leaves us with a .754 rate of interest, which seems too high. Double check where you're typing from
Answer:
Apple- 14 Maple- 154
Step-by-step explanation
Since 11 x n - n is equal to a number that ends in 10, 20 etc. and the number has to be a multiple of 11 for the maple tree, and the difference has to stay the same throughout two all we need to find is 15 x n = a number that is divisable by 10. 15 x 10 = 150 so that's the age of the trees this year, and the difference between the trees is 140 so it corresponds with our rule. and the multiple of 11 that the difference is 140 is 11 x 14 = 154 and 154 - 11 = 140. Therefore the apple tree is 14 years old and the maple tree is 154 years old.
Answer:
Step-by-step explanation:
3p – 1 = 5(p – 1) – 2(7 – 2p) 3 -9 -10 First Distribute
3p-1= 5p-5-42+12p-9-10 Simplify all like factors
3p-1=17p-66 Add 66 on both sides
3p+65=17p Subtract 3p from both sides
65=15p Divide both sides by 15
p=4.3
if it is a 100
3p – 1 = 5(p – 1) – 2(7 – 2p) 3 -9 -100 First Distribute
3p-1= 5p-5-42+12p-9-100 Simplify all like factors
3p-1=17p-156 Add 156 on both sides
3p+155=17p Subtract 3p on both sides
155= 15p divide both sides by 15
10.3=p
