The answrr is B, 60%. 45/75 equals 60, so it should be 60%.
Step-by-step explanation:

If we were to put this in terms of a venn diagram, we would have 360 owning only brand X, 500 owning only brand Y, and 80 in between, owning both. Therefore, 80 out of the 580 owners of brand Y may have X as well, which we put into fraction form 80/580, and reduce to 4/29.

Oh gurly!!!! Just use a calculator but I’ll answer this one for you okay? Now how I’d do it without a calculator is subtract. Subtract if it asks you to add and add if it asks for subtraction.. it may be confusing but I’ll explain. 9.7-5.4=4.3
When you add a negative to a positive it subtracts the positive.
