Line 1 as filled in curcle means smaller/bigger or equal to
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:

she has 10 pounds of potting soil.
<em>Answer:</em>
y = 100(6.3246^x)
<em>Explanation:</em>
Ao*k^x = A where Ao is the initial amt
k = constant factor
x = time in hrs
A = resulting amt
Write an equation from the 1st statement, x = 2 hrs, find k
100 * k^2 = 4000
k^2 = 4000%2F100
k^2 = 40
k = sqrt2840%29
k = 6.3246
The equation
:
y = 100(6.3246^x)
