X + y = 3,500 . . . (1)
x – y = 2,342 . . . (2)
(1) - (2) => 2y = 1158
y = 1158/2 = 579
x = 3500 - 579 = 2921
Therefore, he had 2,921 contempolary titles and 579 classic titles.
The answer is B; $ 59.00. All you have to do is multiply the price times 4 and then subtract that from 100. Then do it again and 59 should be your answer.
P = $1,100
r = 7.25% = 0.0725
A= P(1+r)^t
⇒ 6600 = 1100(1+0.0725)^t
⇒ 6600/1100 = 1.0725^t
⇒ 1.0725^t = 6
Use log to solve it
log(1.0725^t) = log 6
⇒ t * log 1.0725 = log 6
⇒ t * 0.0303973 = 0.7781512
⇒ t = 0.7781512/0.0303973
⇒ t = 25.599 ≈ 25.60 years
Answer:
0.00007935
Step-by-step explanation:
7.935 x 10 to negative 5 power can be written as:
7.935 x 10^(-5)
A trick to finding 10 to the x power, x is the number of 0's. So 10^5 = 100000

When dividing by tens, move the decimal to the left by the amount of 0's
So our answer is 0.00007935
