Answer: B. 24 - 24 x r = 4.32
Explanation:
The percent tip can be found by using the formula: tip = bill x (tip percentage in decimal form)
In this case, Diego's bill was $24 and the tip he paid was $4.32. To find the tip percentage, we can divide the tip by the bill:
tip / bill = 4.32 / 24 = 0.18
To convert the decimal to a percentage, we can multiply the decimal by 100: 0.18 x 100 = 18%
The tip percentage is 18%
So, option B. 24 - 24 x r = 4.32 is the equation that will help find the percent tip that Diego gave the server.
