Barb exercises for 14 hours in one week how many hours dose she exercises in 32 weeks

Multiply the number of hours she exercises in 1 week by the total number of weeks she exercises:

14 hours per week x 32 weeks = 448 total hours.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.
