Answer:
12
Step-by-step explanation:
Given that:
Daily wages paid to a saleswoman = $80
Wages paid for each sale made by her = $6
Target of today's earnings = more than $150
To find:
Least number of sales to be made so that the total earnings today is more than $150.
Solution:
Number of sales for today = [tex]x[/tex]
Wages for one sale = $6
Wages for [tex]x[/tex] number of sales = $6[tex]x[/tex]
Total earnings = Per day sales + Wages for [tex]x[/tex] number of sales > $150
[tex]80 + 6x > 150[/tex]
we need to solve for above inequality to find the least number of sales to be made to meet the goal.
Subtracting 80 from both sides:
[tex]\Rightarrow 6x>70\\[/tex]
Dividing both sides by 6:
[tex]\Rightarrow x > 11[/tex]
Therefore, at least 12 sales must be made.
