Explanation:
So, I know a lot of people won't do it this way, but this is how I would do it.
First, multiply each expense by eight (eight for the eight days)
$55 x 8 = 440
$25 x 8 = 200
$129 x 8 = 1032
Next, take the three answers and add them together:
440 + 200 + 1032 = 1672
Lastly, divide 1672 by four (four for the four friends)
1672/4 = 418
There you go! Here is your answer. Each friend paid $418
Hope I helped! :D
We need to write system of equations for this problem. Reading text we write 1 equation by 1.
first lets name our variables
x - Kiana cards
y - Gary cards
z - Monty cards
m - Willa cards
x = y-3 which we can write as y = x+3
z = x + 7
m = 2z
x + y + z + m = 74
I think easiest way to solve this is to express all variables in last equation and solve for x.
x + x+3 + x + 7+ 2x + 14= 74
5x = 50
x = 10
now we just calculate cards given to each friend
y = 13
z = 17
m = 34
Answer:
14.
