Gina spent $54 for a total of 15 bags of treats for the cats and dogs at the shelter.She paid $3 for each bag of cat and $4 for each bag of dog treats.

Respuesta :

The number of bags of cat treat is 6 and the number of bags of dog treat is 9.

Let

x = number of cat treat

y = number of dog treat

She bought a total of 15 bags for treat for cat and dog. Therefore,

Total number of treats:

  • x + y = 15

She spent $54 on the total treats. Therefore,

Total cost of treats:

  • 3x + 4y = 54

Therefore,

x + y  =15

3x + 4y = 54

3x + 3y = 45

3x + 4y = 54

y = 9

x = 15 - 9

x = 6
