Bonjour,
j'ai trouvé cet exercice que je n'arrive pas a resousdre par moi meme.
apres un long moment de recherche, je me tourne vers vous
"There are three types of tickets available for a concert: orchestra,
which cost $12 each; balcony, which cost$9 each: and box, which cost $25
each. There were "P" orchestra tickets , "B" balcony tickets, and "R"
box tickets sold for the concert.
You need to create math expression witch will give percentage of
orchestra tickets.
"P", "B", "R" are unknown variables."
a bon entendeur, ....
merci!
