Answer:
28
Step-by-step explanation:
I am assuming that "voice" is boys. So there were 20 girls and 10 boys. The number of girls decreased by 30%, so the amount of girls now is 70% of the old amount, so there are 7/10 * 20 girls now = 14 girls. The number of boys increased by 40%, so the number of boys now is 14/10 the original number of boys, so there are 14 boys now. 14+14=28 members on the swimming team

Let
x----------> Dewi quantity of money
y----------> Sheila quantity of money
we know that
(x-23)=(3/5)*y-------> equation 1
(y-42)=(4/5)*x-------> equation 2
using a graph tool----------> to calculate the system of equations
see the attached figure
the solution is the point (92.692,116.154)
x=92.692
y=116.154
Dewi quantity of money is $92.69
Sheila quantity of money is $116.15
the answer is
Dewi have $92.69
The best answer to this statistic question would be 15.7% or, if rounded off, 16%. This is because those students who have GPAs are approximately at least 1 standard deviation away from the mean and more - which means that 84% of the GPAs are less then 3 pounds. I subtracted 84 from 99.7 (which is the whole distribution's percentage) and came up with 15.7.
