Answer to Question #22876 in Algebra for Jennifer Smith

Question #22876
The local grocery store offers two varieties of salami at the deli counter. The price per pound of the second, more expensive, salami is $3 more than twice the price per pound of the first variety. If Lisa buys 2 pounds of each type of salami and her total price is $29.94, find the price per pound for each variety of salami.
Expert's answer
x - more expensive sausage
y - other sausage

1. Lisa buys 2 pounds of each type of salamiand her total price is $29.94, so 2x+2y=29.94
2. The price per pound of the second, more expensive, salami is $3 more
than twice the price per pound of the first, so x=2y+3

Se we get a system of equations

2x+2y=29.94
x=2y+3
solving it we obtain
x=10.98$
y=3.99$
