Answer:
e)$141,750
Step-by-step explanation:
Let be
AG = Members with advanced degrees
BG = Members with a bachelor's degree
DG = Members with a no degree
In a sample of 50 members it is expected a total of members for every group as follows
For AG = 30 * 0.5 = 15
For BG = 50 * 0.5 = 25
For DG = 20 * 0.5 = 10
The expected donation for every group would be the number of members by the 5% of their incomes
For AG = 15 * 0.05 * $75,000 = $56,250
B For G = 25 * 0.05 * $54,000 = $67,500
For DG = 20 * 0.05 * $36,000 = $18,000
Total donation is the sum = $141,750
2x+10=6 can be simplified to 2x=-4
x=-2
