Answer:
[tex]\huge\boxed{\text{Tip: } \$ 11}[/tex]
[tex]\huge\boxed{\text{Total Cost: } \$ 65.65}[/tex]
Step-by-step explanation:
In order to find the percent of something, we need to convert the percent into a decimal.
50% of x can be represented as [tex]0.5x[/tex], as 50% is half of x and so is 0.5.
This means that 20% of 54.65 will be [tex]54.65\cdot 0.2[/tex], which is $10.93.
Rounding to the nearest dollar gets us $11.
To find the total cost, we can add $11 (the tip) to the previous cost of $54.65.
[tex]54.65+11=65.65[/tex]
Therefore, the total cost of the dinner would be $65.65
Hope this helped!
