Answer:
"Work out the percentage discount offered with the family ticket option."
A = adult (55 euro) C = children ( 45 euro )
( A x 2 ) + ( C x 2)
= (55x 2) + ( 45 x 2 )
= 110 + 90
= 200 base value of prices of ticket :
Family = F ( in point we want to find the percentage discount offered with the family ticket option ) we need :
200 -170= 30
F =30 : 200
F = 0.15
F= 15%
