Shayanne bought a bag of chips and a burger for $4. Griff bought 2 bags of chips and 3 burgers for $10.50. How much does a bag of chips cost?

Respuesta :

Answer:

Cost of each bag of chip = $1.5

Step-by-step explanation:

Given:

1 bag chips and 1 burger cost = $4

2 bag chips and 3 burger cost = $10.50

Find:

Cost of each bag of chips

Computation:

Cost of each bag of chip = c

Cost of each bag of burger = b

So,

c + b = 4 ......  eq1

2c + 3b = 10.50 ..... eq2

Eq1 x 2

2c + 2b = 8 ....... eq3

From eq2 - eq3

b = 2.5

From eq1

c + b = 4

c + 2.5 = 4

c = 1.5

Cost of each bag of chip = $1.5
