1. In an orchestra, 60% of the musicians play string instruments, and the remainder play woodwind, brass, or percussion instruments. If the orchestra has 130 members, how many musicians do not play string instruments?

 

2. How many natural-number factors does N have if N=2^4*3^3*5^2*7^2?

60% play wind        that means   40% do NOT play wind instr

 

40% x 130    =    .4 x 130 = 52
