Step-by-step explanation:
let adult ticket be y
and children's ticket be
therefore, y=2x ---- eq(i)
Mrs and Mr Brown with their children's cost = $3.15
considering that Mrs and Mr Brown are adults.
2y+5x=3.15
after substituting value of y from eq(i) -
we get
2(2x)+5x=3.15
9x=3.15
x=0.35
after getting x's value, we can substitute the value of x in eq (i) therefore y=2(0.35)
=0.7
therefore, adult ticket's value = $0.7 or 7€
and children ticket's value = $0.35 or 3.5€
