Answer:
Therefore, we conclude that the amount of an 18% tip on the food total is $8.19.
Step-by-step explanation:
We know that bill for a food is $45,50. We calculate the amount of an 18% tip on the food total. Therefore, we use the proportion to calculate the required 18%. We get
45.5:100%=x:18%
100·x=45.5·18
100x=819
x=819/100
x=8.19
Therefore, we conclude that the amount of an 18% tip on the food total is $8.19.
