(a) What fraction of the total sales did each salesperson sell? Show all of your work.

Answer 1

`\text{Fraction of Sara sold }= (1675)/(2587)`

`\text{Fraction of Kenny sold }= (684)/(2587)`

`\text{Fraction of Leila sold }= (228)/(2587)`

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.

`\text{Fraction of Sara sold }=\frac{\text{Sara total sold}}{\text{Total sale by all three}}`

`\text{Fraction of Sara sold }=(3350)/(5174)\Rightarrow(1675)/(2587)\approx 64.75\%`

`\text{Fraction of Kenny sold }=\frac{\text{Kenny total sold}}{\text{Total sale by all three}}`

`\text{Fraction of Kenny sold }=(1368)/(5174)\Rightarrow(684)/(2587)\approx 26.45\%`

`\text{Fraction of Leila sold }=\frac{\text{Leila total sold}}{\text{Total sale by all three}}`

`\text{Fraction of Leila sold }=(456)/(5174)\Rightarrow(228)/(2587)\approx 8.8\%`
