Duckling computers manufactures three models of personal computers: cannon, clone, and slow-but-safe. To assemble a cannon model computer you need 12 hours of assembly, 2.5 to test it, and 2 more to install their programs. For a clone it requires 10 hours of assembled, 2 to test it, and 2 to install programs. And finally, for a slow-but-secure it requires 6 for assembly, 1.5 to test it, and 1.5 to install programs. If the The factory has 556 hours per month for assembly, 120 for testing, and 103 hours for software installation, how many computers can be produced per month?
