$7.95
1) Considering that the dinner cost was $53, and we need to find out the tip equivalent to 15% of that cost, we need to calculate it this way:
2) We can multiply that 53 by 15% and then simplify it to get the answer:
![53*(15)/(100)=(795)/(100)=7.95](https://img.qammunity.org/2023/formulas/mathematics/high-school/8z5rvzv2rl01kai8zz68z33tjuf4gh2646.png)
