The manager of the ice cream shop noticed that 90% of all club members brought along a family member who spent an average of $18 in the shop. The tax on
their bill was 5.5%.What was the total amount spent by the family members in one year? What would each family member spend, on average, to generate 5,000 in income before sales tax?
To find the total amount spent by family members in one year, we need to first determine the average amount spent by each family member, and then multiply it by the total number of family members.
1. Start by determining the average amount spent per family member:
- We are given that 90% of all club members bring along a family member.
- Therefore, we can assume that each club member corresponds to one family member.
- If the average spending per family member is $18, it means that each club member spends $18.
2. Find the total number of club members:
- Since each club member corresponds to one family member, we can assume that the total number of club members is the same as the total number of family members.
3. Calculate the total amount spent by family members in one year:
- Multiply the average spending per family member ($18) by the total number of family members.
Next, let's calculate the number of family members needed to generate $5,000 in income before sales tax.
1. Determine the income before sales tax per family member:
- We are given that each family member's spending generates income before sales tax.
- The total income before sales tax is $5,000.
- Divide the total income before sales tax ($5,000) by the number of family members.
Now, let's put this into practice.
1. Total amount spent by family members in one year:
- Assume there are 100 club members (and thus 100 family members).
- Average spending per family member: $18
- Total amount spent = $18 x 100 = $1,800
2. Number of family members needed to generate $5,000 in income before sales tax:
- Income before sales tax per family member = $5,000 / Number of family members
Please note that the exact number of family members needed to generate $5,000 in income before sales tax cannot be determined without knowing the income before sales tax per family member. This value is missing from the information provided.
