If 105 customers were the total, and 35% prefers cake, we must calculate 35% of 105, then we must do 105 multiplied by 35%, we can doit transforming the 35% in the fraction notation:
![35\%=(35)/(100)](https://img.qammunity.org/2023/formulas/mathematics/college/5fy1t7vjyvk97l23ew6w8we3dsxxyuwg9w.png)
And the multiplication
![105\cdot(35)/(100)=36.75](https://img.qammunity.org/2023/formulas/mathematics/college/go9ot8so1o8ca15rsvz29la7ukqehqki2t.png)
Therefore, if we round it to the nearest whole number, the number of customers that prefer cake is 37.
