What is the answer to becca took her cans and plastic bottles to the recycling center. she brought 72 pieces and collected $92. becca receives $1 and $2 per plastic bottle in writing systems of equations?

C + b = 72because the is a total of 72 cans and bottles
1c + 2b = 92because each can is worth $ 1 and each bottle is worth $ 2c is the number of cans and b is the number of bottles...and she collected $ 92

so ur system is :
c + b = 72
1c + 2b = 92

Ithink if ur looking for a ratio it would be 12: 3
