Answer:
$22.43
Explanation:
We can start by finding the amount that they should tip. The total bill is $78, so we should take 15% of 78 and add it to the total.
0.15 * 78 = 11.7
78 + 11.7 = 89.7
This means that the total cost of the bill, with a tip, is $89.70.
Since there are 4 people, we have to split this total into 4 if they all want to pay equally.
89.70 / 4 = 22.425 = $22.43 !

Answer:
4
Step-by-step explanation:
From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6
The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6
= [8 + (-7) + 9 + 11 + (-3) + 6] / 6
= 24 / 6
= 4
=
6.) triangles; 6 units
7.) 5 x 6; 30 units
8.) 72 units
9.) 84 units
