Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change. How much did each avocado cost i

Delvig [45]

Answer:

$1.10

Step-by-step explanation:

We have been that Alex went to the grocery store and bought 5 avocados. He paid $10 and received $4.50 in change.

First of all, we will find amount paid for 5 avocados by subtracting $4.50 from $10.

$\text{Amount paid for 5 avocados}=\$10-\$4.50$

$\text{Amount paid for 5 avocados}=\$5.50$

Now, we will divide $5.50 by 5 to find cost of each avocado.

$\text{Cost of each avocado}=\frac{\$5.50}{5}$

$\text{Cost of each avocado}=\$1.10$

Therefore, the cost of each avocado is $1.10.
