d. 95.5

Explanation:

Based on the information provided within the question it can be said that if in this scenario Carla scored a 95 on the first test and the variable "x" in the equation represents the first test, then we can plug in the 95 and solve for y. Therefore,

y = 10 + (0.9*x)

y = 10 + (0.9*95)

y = 10+85.5

y = 95.5

So we can see that the predicted final test score is that of 95.5
