Answer:
She should purchase a disability insurance if $1,150
Explanation:
To calculate the amount of individual disability insurance she should purchase, we use the mathematical equation below;
Required amount of disability insurance = Monthly income - work related expenses- Employer’s contribution
From the question
Monthly income = $1800
Work related expenses = $50
Employer’s contribution = $600
Substituting these values, we have;
1800-50-600 = $1,150
