The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.
