Question

Rex sold 30 avocados that were small and large. He sold the small avocados for 35 cents and the large ones for 50 cents. If Rex made $13.50, how many of each kind
did he sell?

Answer 1

Answer:

Rex sold 10 small avocados and 20 large avocados.

Step-by-step explanation:

Let us assume the number of small avocados and large avocados sold as 'x' and 'y' respectively.

Therefore, the equation framed is:

$35x+50y=1350$

On simplification,

$7x+10y=270$

Also, as Rex sold only 30 avocados,

$x+y=30$

Subtracting 7 times the second equation from the first equation, we get:

$3y=60\\y=20$

Substituting in the second equation, we get:

$x=10$

Therefore, Rex sold 10 small avocados and 20 large avocados.
