Step-by-step explanation:
Suppose a number = A
4(11-A) = 60
(11 - A) = 60/4
11 - A = 15
11 = A + 15
A + 15 = 11
A = 11 - 15
= -4

Dave invested approximately $29,629.63 into Oil companies.
Step-by-step explanation:
8/9 (100,000) = i
i= $88,888.89
2/3(88,888.89)=c
c = $29,259.26
1/2(29,259.26)=o
o= $29,629.63
The answe is simply 4/15. to find the answer put the whole number on the bottom and the other number on top and simplify as far as possible by dividing by the common number.
Answer:
11.5%
Step-by-step explanation:
Let the number of smokers before ban = 100
Decrease in 1st month = 3% , of 100 = 3
Smokers after 1st month = 100 - 3 = 97
Decrease in 2nd month = 2%, of 97 = 1.94
Smokers after 2nd month = 97 - 1.94 = 95.06
Decrease in 3rd month = 5%, of 95.06 = 4.75
Smokers after 3rd month = 95.06 - 4.75 = 90.31
Decrease in 4th month = 2%, of 90.31 = 1.80
Smokers after 4th month = 90.31 - 1.80 = 88.51
- Decrease in smokers after 4th month = (Decrease / old value) x 100
[ (100 - 88.51) / 100 ] x 100 = (11.49 / 100) x 100
= 11.5%
