Question 123424
Since there are 35 reptiles, we can conclude that {{{x+y=35}}} (x represents the number of iguanas and y represents the number of con snakes). In addition, since the total cost of selling the animals are $1975.00, we can also conclude that {{{75x+25y=1975}}}. Now that we have two system of equations, we can use any method to solved it. I recommend substitution.

Equations:
{{{x+y=35}}}
{{{75x+25y=1975}}}
Solution:
{{{x=22}}}and{{{y=13}}}
The store sold 22 iguanas and 13 corn snakes.
