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 = 72 ... because the is a total of 72 cans and bottles

1c + 2b = 92 ... because each can is worth $ 1 and each bottle is worth $ 2 ... c 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
