If the total bill comes to $110.05, we know that we are going to have to take 15% of this for his tip.
So we convert 15% to a decimal by dividing by 100:
Then we multiply this by the amount of the bill:
So if we round this to the nearest cent, we get $16.51.
Therefore, Alberto's tip will be about $16.51.
Answer:
d. 32.9
Step-by-step explanation:
To find c, we'll use the Law of Sines that says:
And we'll isolate a to get:
We first need to find A, which is easy. The sum of the interior angles of a triangle is 180 degrees... and we already have 2 of them, so:
A = 180 - 90 - 47.3 = 42.7
(converted 47°18' to 47.3)
Then we will plug-in the information we already have
So, let's round it to 32.9 to match the answer number D.
