Final answer:
The sale price of the jacket is $48.
Step-by-step explanation:
To find the sale price, we can set up a proportion using the given ratio. Let's call the sale price 'x'. The proportion can be written as 3/4 = x/64. To solve for 'x', we can cross-multiply and solve the resulting equation: 3 * 64 = 4 * x. Simplifying further, we get 192 = 4x. Dividing both sides by 4, we find that x = 48. Therefore, the sale price is $48.
