Answer:
The steps have been shown in the solution below
Step-by-step explanation:
LHS=RHS Hence, proved.
Let n be the number of lbs of nuts.
Let r be the number of lbs of raisins.
9n + 3r = 60 * 5 = 300 .............(1)
n + r = 60
n = 60 - r ...............(2)
Plugging the expression for n in (2) into (1) we get:
9(60 - r) + 3r = 300
which expands to:
540 - 9r + 3r = 300 .............(3)
Simplifying and rearranging (3) we get:
-6r = -240
Therefore r, the weight of raisins = 40 lbs
and the weight of nuts is 60 - 40 = 20 lbs

(b) The monthly savings of Juan is $200.
(a) The monthly saving of Juan is $900.
(c) The monthly saving of Juan is $3,600.
As we know that
Savings = Income - expenses
So based on the above formula, the monthly savings in each case is as follows:
(b)
Monthly saving is
= $3,600 - $3,400
= $200
(a)
Monthly saving is
= $3,600 - $2,500
= $900
(c)
Monthly saving is
= $3,600 - $0
= $3,600
Here we assume the x be zero.
Therefore we can conclude that
(b) The monthly savings of Juan is $200.
(a) The monthly saving of Juan is $900.
(c) The monthly saving of Juan is $3,600.
