To solve this problem, let us first assign some variables. Let us say that:
x = amount of large stuffed animals sold
y = amount of small stuffed animals sold
a = price of large stuffed animals
b = price of small stuffed animals
Therefore the equation of the total earning is:
Total earning = a x + b y
We know that:
Total earning = $65
a = $9
b = $4
Therefore:
65 = 9 x + 4 y
It was also stated that equal amount of x and y are sold, therefore:
x = y
Hence,
65 = 9 x + 4 x
65 = 13 x
x = 5
and y = 5
To complete the sentence:
Tory sold 5 small stuffed animals and 5 large stuffed animals.
