Answer:
1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
x is the amount of sodium in 1oz of chips.
y is the amount of sodium in 1 cup of soda.
Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium.

Answer:
6.58 years
Step-by-step explanation:
Step one:
Given data
Principal=$9500
rate= 5%= 0.05
Final amount= $13200
Required:
The time t
Step two
The expression for the compound interest is

t = ln(A/P) / r.
substitute
t = ln(13200/9500) /0.05
t= ln(1.39)/0.05
t=0.329/0.05
t=6.58 years
