We need to use the information given from the question to help us make our systems of equations
We know that Blow pops cost $0.50 each
We also know that Snickers cost $0.60 each
She bought 30 total pieces of candy
She spent a total of $16.80
First, lets make the systems of equation for the amount of candy she bought
We would represent blow pops as "b", and snickers as "s"
We know that she bought 30 pieces of candy, so our equation would = 30
We add b and s to get 30, so our equation would be:
b + s = 30
Systems of equation for the cost:
Represent blow pops as "b", and snickers as "s" for this equation too
We know that Blow pops cost $0.50 each and that Snickers cost $0.60 each
We know she spent a total of 16.80 dollars, so the equation would = 16.80
You would add 0.50b and 0.60s to get 16.80
The equation would be
0.50b + 0.60s = 16.80

Answer:
b + s = 30
0.50b + 0.60s = 16.80
