Answer 1

A: Second option

B: 18%

Explanation:

PART A

The second option

0.40c(0.15) + 0.60c(0.20)

If we have 40% men, and 15% of them are advanced

we can say 40% x 15% x c which is the same as 0.40 x 0.15 x c

Same thing for the women

0.60 x 0.20 x c

PART B

0.40c(0.15) + 0.60c(0.20)

= 0.06c + 0.12c

= 0.18c which is the same as 18% of c
