A church congregation has 149 members, and each member donates 10% of their income to the church. If the church collected 335250 dollars last year from its members, what would be the mean contribution of its members? What about the mean income of its members?
Please help, I'm so lost on what to do.
$335,250 / 149 = mean contribution
Let x = the income of all its members.
.1x = 335,350
x = total income of all members
x/149 = mean income of the members

Thanks so much!
To find the mean contribution of the church members, we need to divide the total collected amount by the number of members.
Step 1: Divide the total collected amount by the number of members:
Mean Contribution = Total Collected Amount / Number of Members
Mean Contribution = 335250 dollars / 149 members
Mean Contribution ≈ 2250.34 dollars (rounded to two decimal places)
So, the mean contribution of the church members is approximately 2250.34 dollars.
To find the mean income of the church members, we need to solve for their income based on the given information and then calculate the mean.
Step 1: Calculate the total collected amount as a percentage of the total income:
Total Collected Amount = Total Income × 10%
335250 dollars = Total Income × 0.10
Step 2: Divide both sides of the equation by 0.10 to isolate the total income:
Total Income = 335250 dollars ÷ 0.10
Total Income = 3352500 dollars
Step 3: Divide the total income by the number of members to find the mean income:
Mean Income = Total Income / Number of Members
Mean Income = 3352500 dollars / 149 members
Mean Income ≈ 22516.78 dollars (rounded to two decimal places)
So, the mean income of the church members is approximately 22516.78 dollars.
