Question

Corinne bought 5 bags of chips and 4 jars of dipping sauce for $21.82. At the same prices, Ginger bought 4 bags of chips and 3 jars of dipping sauce for $16.86. What is the price of one jar of dipping sauce?

Answer 1

The price of one jar of dipping sauce is $2.98

Explanation:

Let

x ----> the price of one bag of chip

y ----> the price of one jar of dipping sauce

we know that

Corinne

`5x+4y=21.82` ----> equation A

Ginger

`4x+3y=16.86` ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (1.98,2.98)

see the attached figure

therefore

The price of one bag of chip is $1.98

The price of one jar of dipping sauce is $2.98
