Try this explanation+solution: 1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation. 2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π). 3. answer: y=5sin2x.
First multiply 20 by .3 (30%) This will give you a product of 6. Subtract 6 from 20 (14) $14 added to $20 is equal to $34 Ramon spent $34 on the pullovers
