Question

I have a question

Answer 1

You could start with setting variables.
\(\text{Charlene} = x \Longrightarrow \text{Kristi} = x - 150, \text{Sacha} = x + 100\)

Answer 2

Forming an equation, you get: \(x + (x - 150) + (x + 100) = 2050\)

Answer 3

Yea,

Charlene = 700
Krishi = 550
Sacha=800

I just made a mistake in adding

Answer 4

Anyway Thanks

Answer 5
