Solve the problem.A study of ice cream consumption over 30 four-week periods in the early 1950s gives rise to the equation C = 0.3520 + 0.0786 sin(0.4806? - 0.1691) where ? is the number (from 1 to 30) of the four-week period and C is the ice cream consumption in pints per capita. Determine the consumption for the tenth four-week period. Round answer to the nearest 0.001 pint.
