In cryptography, inverse functions are used by government agencies and other businesses to encode and decode information. The alphabet is A = 1, B = 2, C = 3, ... If the encoding function is y=4x+7 and the code numbers are 15, 67, 55, and 87, what is the encoded word? (Find the y values of the inverse.)
