Answer:
[tex]\text{Fraction of Sara sold }= \dfrac{1675}{2587}[/tex]
[tex]\text{Fraction of Kenny sold }= \dfrac{684}{2587}[/tex]
[tex]\text{Fraction of Leila sold }= \dfrac{228}{2587}[/tex]
Step-by-step explanation:
The three salespeople for a local advertising firm are sara, Kenny and Leila.
Sara sold total ads = $3350
Kenny sold total ads = $1368
Leila sold total ads = $456
First we calculate total sale of all three = 3350 + 1368 + 456 = $5174
We need to find fraction of total sale with each person sell.
[tex]\text{Fraction of Sara sold }=\dfrac{\text{Sara total sold}}{\text{Total sale by all three}}[/tex]
[tex]\text{Fraction of Sara sold }=\dfrac{3350}{5174}\Rightarrow\dfrac{1675}{2587}\approx 64.75\%[/tex]
[tex]\text{Fraction of Kenny sold }=\dfrac{\text{Kenny total sold}}{\text{Total sale by all three}}[/tex]
[tex]\text{Fraction of Kenny sold }=\dfrac{1368}{5174}\Rightarrow\dfrac{684}{2587}\approx 26.45\%[/tex]
[tex]\text{Fraction of Leila sold }=\dfrac{\text{Leila total sold}}{\text{Total sale by all three}}[/tex]
[tex]\text{Fraction of Leila sold }=\dfrac{456}{5174}\Rightarrow\dfrac{228}{2587}\approx 8.8\%[/tex]
