Department 81809

Three times more boys than girls go to the Jude section. If three more girls started dating, there would be twice as many boys as girls.
A) determine how many go to the girls' section
B) determine how many children attend the department in total.

Correct answer:

d =  6
x =  24

Step-by-step explanation:

$$\begin{gathered} c=3d \\ c=2\cdot (d+3) \\ 3d=2(d+3) \\ 3\cdot d=2\cdot (d+3) \\ d=6 \\ d=\frac{6}{1}=6 \\ d=6 \end{gathered}$$

$$\begin{gathered} c=3\cdot d=3\cdot 6=18 \\ x=c+d=18+6=24 \end{gathered}$$
