Final answer:
To find the number of iguanas sold, we can set up an equation and solve for the number of iguanas.
Step-by-step explanation:
To find the number of iguanas sold, we can set up an equation using the given information. Let x be the number of iguanas sold. The total amount received from selling iguanas would be x * 75. The total amount received from selling corn snakes would be (35 - x) * 25. We can add these two amounts together and set it equal to $1975.
So, the equation is: x * 75 + (35 - x) * 25 = 1975.
Now, we can solve this equation to find the value of x. By simplifying and solving, we get: 50x + 875 = 1975. Subtracting 875 from both sides gives 50x = 1100. Finally, dividing both sides by 50 gives x = 22.
Therefore, Reba's Reptile Store sold 22 iguanas.
