Step-by-step explanation:
there you go, I think that's right but it's been awhile since I've had to do mode mean median and range
X<-6 with the line under it is the answer, you would flip the sign when u divide
The amount spent by Seedevi is $66
<h3>How to determine the amount spent by Seedevi?</h3>
From the question, the given parameters are:
Seedevi = half as much money as Georgia,
Seedevi = $6 more than Amy
The three of them = $258
To solve this question, we use the following representations
x = Seedevi
y = Georgia
z = Amy
So, we have the following equations
x = 0.5y
x = 6 + z
x + y + z = 258
Make y and z the subjects
y = 2x
z = x - 6
Substitute y = 2x and z = x - 6 in x + y + z = 258
x + 2x + x - 6 = 258
Evaluate the like terms
4x = 264
Divide by 4
x = 66
Hence, the amount spent by Seedevi is $66
