a wildlife center presents a program about birds of prey. the center charges a basic fee of $325 and an additional fee for each

Rainbow [258]

The exhibition of 7 birds will cost $2,450

<h3>How to calculate the total cost ?</h3>

The wildlife center charges a basic fee of $325 for a bird exhibition

When 5 birds were exhibited, $125 additional fee was charged

The additional fee for a bird is

= 125/5

= 25

Therefore the total cost of exhibiting 7 birds can be calculated as follows

= 325 + 25

= 350

350 × 7

= 2,450

Hence the total cost for the exhibition of 7 birds is $2,450
