The rate for one unit of a given quantity is called a(n)

Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

This is different from the first one can someone me
