In this case, the total number of images is 60, and the number of correctly identified images is 35 kittens plus the number of correctly identified tiger cubs. We can represent this as the equation:

(35 + tiger cubs) / 60 > 0.75

To solve for the number of tiger cubs, we can multiply both sides of the equation by 60 and simplify:

35 + tiger cubs > 45

Subtracting 35 from both sides gives us:

tiger cubs > 10

So, to achieve an accuracy of more than 75%, the model must correctly identify at least 11 tiger cubs.
