She will be 75 minutes late because you take the 15 minutes per stop and multiply it by the five stops.
First you find the area of one triangle and multiply it by three. You do (4)(7)=28 and divide that by two to get 14, and multiply that by three to get 42. Then do (7)(7)=49 to get the area of the square, and finally add the two together to get the area of the logo which is 91.
Hello!
First you have to find the differences in the prices
The only difference is that your friend signed up for $30 and you signed up for $50
This means that the lines would be parallel and your cost will be $20 higher than your friends
The answer is $20
Hope this helps!
