Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50

Answer:
Step-by-step explanation:
Hello, first we can develop (x+a)(x+b)
We know that this should be equal to
So, we can identify the coefficients of the like terms
1 = 1 (terms in
1 = a + b (terms in x)
-72 = ab (constant term)
72 is 8 * 9 so, -72=9*(-8)
and we have 9 - 8 =1
so, a = 9 and b = -8
Thank you
(a) ln(3)/30 = 0.0366
_____
The solution to the differential equation is
.. p(t) = p0*e^(0.0366t)
then
.. p(30) = p0*e^1.098 = 3.00*p0 . . . . to 3 significant figures
The answer to this problem is 51
