r = continuous growth rate
revenue t years after 2013 = 54.5×10⁹×e^(rt)
74.6×10⁹ = 54.5×10⁹×e^(2r)
e^(2r) = 74.6/54.5
2r = ln(74.6/54.5)
r = ½ln(74.6/54.5) ≅ 0.15697 = 15.697% per year
Hope this helps!
Let x= the number of bags of soil
20x(less than or equal to sign) 300
divide both sides by 20 and you get x is less than or equal to 15
Now, to find how many people are not there, all you have to do is subtract the amount of seats and the people there.
112- 70= 42
Now since there are 7 seats per row and 42 is divisible by 7, you can divide 42 by 7.
42÷7= 6
So, 6 rows were empty.
5/8 = 0.625
6 / 9.6 = 0.625
12.8 * 0.625 = 8
x = 8
