on a family outing tyler bought 5 cups of hot cocoa and 4 pretzels for $18.50. Some of his family members would like a second serving, so he went back to the same food stand and bought another 2 cups of hot cocoa and 4 pretzels

Respuesta :

Answer:

5c+4p = 18.50

2c+4p = 11.20

Cost of cup = $2.4

cost of pretzels = $1.625

Step-by-step explanation:

Note:

2 cups of hot cocoa and 4 pretzels for $11.30

Computation:

5c+4p = 18.50........eq1

2c+4p = 11.30........eq2

Where c = cost of cup

p = cost of pretzels

From eq1 - eq2

3c = 7.20

c = 2.4

Cost of cup = $2.4

5c+4p = 18.50

5(2.4) + 4p = 18.50

p = 1.625

cost of pretzels = $1.625
