Equation:
since its a 15% increase its:
100+15=115
115/100=1.15 (changing from percentage to decimal)
1.15x=$10,120
x=$10,120/1.15
x = $8,800
the next given is a 10% increase so we do the same thing: 100+10=110
110/100=1.10 (changing from percentage to decimal)
1.10y=$8,800
y=$8,000
So the answer for how much it was raised 2 years ago is:
$8,000

This appears to be a composite function situation where you find the value of t(x) and sub that in for the x in c(x). If x = 4, then t(4) = 4(4) + 3 and t(4) = 19. Sub that 19 in for x in c(x) to get 2(19) + 5 which is 43. So 43
Answer:
Step-by-step explanation:
27 is a perfect cube for and 729 is a perfect cube for
now you can pull out the numbers from under the root, for t (divide the exponent by 3)
now simply to
Answer: x=2 - 1/2 x ㏒(16/2953125)
Step-by-step explanation:
- log (28^2) + log(525^-3) + 2x=log(10^4)
- log(28^2 x 1/523^3) + 2x=4
- log(28^2/525^3) + 2x=4
- log (112/75 x 75 x 525) + 2x=4
- log(16/2953125) + 2x=4
- 2x=4-log(16/2953125)
- <u><em>x=2-1/2 x log(16/2953125)</em></u>
