c=36+g
c:g:s=5:2:1
The ratio gives us two equations so that's three equations in three unknowns. Actually we're after the total t; let's put that in to solve for directly.
c:g:s:t = 5 : 2 : 1 : 5+2+1
We turn the ratio to fraction equations. s has the one; let's write everything in terms of s.
c/s = 5/1, g/s = 2/1, t/s = 8/1
Clearing the fractions,
c = 5s, g = 2s, t = 8s
Our other equation is
c = 36 + g
Substituting in for c and g,
5s = 36 + 2s
Solving,
3s = 36
s = 12
That's right; let's just get the total t.
t = 8s = 72

The numbering of the choices was defined in the attached file please find it.
In the question except for option b, all choices were correct, that can be defined as follows:
- Citizens also believe because they save by buying products at a price, even if the product wasn't required first.
- It's cheaper to take and tough to maintain track of funds without a way to invest (like a bank account).
- Billions of lives were expended on ads and convince consumers to invest money in the junior high rather than saving their union so Hust started his career.
