Answer:

Step-by-step explanation:

Lorenas backpack is has the mass of 10000 grams so in kilograms the mass of Lorenas backpack in kilograms would simply be 10 kilograms
First 700-25=675
Poppy= 2F (F as in Felix, since she sells twice as much)
Alex = (Now equals 2F as well, cus we already took away the 25)
And well.... Felix is just felix so add that all up
F+F+F+F+F=5F
675/5=135!
Now according to that 135 is how many felix sold
Felix=135
Poppy=270
Alex=295
A= adult
C= child
3A+C = 38.3
A+3C = 52
There is no logical way to find the value of each other than guess-and-check.
