<span>just sub in 7 for the variable n
r(7) = 0.009(7)
= 0.063</span>
Step-by-step explanation:
a) if the population is 3000 and it is being multiplied 1.15 than it is 15%. I found this by multiplying 1.15 by 100 to make it percent than anything over 100 is an increase.
b)im not so sure on this one but I think if t = 0 than it would be p= 3000 x 1.15 x0 which would equal 0
c) p = 3000x 1.15 x 24 p = 82,800
Solution:
<u>Note that:</u>
<u>Using cross multiplication:</u>
- (3x)/20 = (4x + 2)/28
- => (3x) × 28 = (4x + 2) × 20
<u>Simplifying both sides:</u>
<u>Subtracting 80x both sides:</u>
- 84x = 80x + 40
- => 84x - 80x = 80x + 40 - 80x
<u>Simplify the LHS:</u>
- => 84x - 80x = 40
- => 4x = 40
- => x = 10
