Answer:
The number of years in which 70% of the mothers in the workforce is 5 years 6 months .
Step-by-step explanation:
Given as :
The percentage of working mothers y can be modeled by the equation
y = 0.0103 x +0.642
where x is the number of years
y is the percentage of mothers
Now , for the percentage of mothers = 70% = 0.7
So, 0.7 = 0.0103 x + 0.642
Or, 0.7 - 0.642 = 0.0103 x
Or, 0.058 = 0.0103 x
∴ x = [tex]\dfrac{0.058}{0.0103}[/tex]
I.e x = 5.6
So, The number of years = x = 5 years 6 months
Hence The number of years in which 70% of the mothers in the workforce is 5 years 6 months . Answer
