Answer:
The jeans are now $24.75.
Step-by-step explanation:
Two ways to do this. Either you multiply 33 by 0.25 and get 8.25 which is 25% percent of the price and then you just subtract $8.25 from $33 and end up with $24.75, OR you can multiple 33 by 0.75 and you end up with $24.75.
1/7 or 14.3%
30% of 750 = 225 (females who study chemistry)
60% of 2250 = 1350 (males who study chemistry)
1575 = total students studying chemistry
P (female chemistry student) = 225/1575 = 1/7 (simplified)
1/7 = 14.3%
1.34
