Use of advanced calculation; calculation of household dependency ration

Based on the above, responses to the following questions will use to initially screen persons to be eligible for the programme:
(a) Immigration Status – BVI Citizen, Belonger, Resident, Work Permit Holder, Work Permit Exempt
(b) Employment Status prior to Mar 11 – Working full time, working part time having secured employment from July 1, 2019 to March 11, 2020
© Primary applicant must be aged 17-65
Once they meet the above, the following questions are to be scored and weighted:

(a) Criteria 1 Employment NOW -the scored responses would be working part time, unemployed covid, unemployed non covid. The individual score is then to be multiplied by 3 to determine their score. Maximum possible is 15.

(b) Criteria 2 Dependency Ratio – No. of non-working household members divided by no. of working household members. The primary applicant in addition to household members are used to calculate. For household members, any person who does not select (full time, part time) are then considered as non-working household members. The score derived after calculating the ratio is then multiplied by 3. Maximum possible score is 15.

© Criteria 3 Number of Disabilities - If a household member has 1 disability, they can score a point. If they have 2 or more disabilities the individual will score a max of 2 points. Each person has the potential of scoring a maximum of 3 points (2 for having 2 or more disability + an additional point if there are household members aged 5 or less or 65 and older). To limit the possible skewing of the scores based on household size, there is a cap of only calculating scores for up to 5 household members. Therefore, the maximum possible score is 3 points for disabilities multiplied by 5 household members = 15 points. So, if there are more than 5 members with each person the maximum points that can be scored having looked at age and disabilities remains 15. Note there is no age calculation on the primary applicant, but if they have disabilities this is scored and does form part of the scoring for that section. However, thereafter the score is divided by 3 to create a score out of 5. This is then multiplied by 2 for the final score for criteria 3.

All eligible persons start with a minimum benefit award of $500. However, the benefit award is increased to the other two tiers $750 or $1000 based on the criteria 2 and 3 improving the scores to fall within the indicated point ranges commensurate with the tiers.

Please note I need to understand how to calculate:
The max scores specific to each criterion
How to cap the disabilities at minimum
