Answer:
The answer is 3
Step-by-step explanation:
If Gina's age is x and Abigail is younger than Gina, Abigail's age will be represented by x-1 given that their ages are consecutive integers.
Translating the fact that the the difference of the square of Gina's age and eight times Abigail's age is 17, we will have the following equation:

We can use the equation above to find Gina's age.
13/20 = 65/100
65/100 = 0.65
hope this helps
