is a stack of 103 credit cards? Explain.

Answer 1

The stack of 103 credit cards is 78.28 mm thick.

Step-by-step explanation:

You can find this by doing 0.76 times 103 = 78.28. So the stack of credit cards is 78.28 mm thick.

Answer 2

78.22 mm thick because you do 103 (how many credit cards) times .76 (thickness of 1 credit card in mm) so 103x.76=78.28mm
