Answer:
A) Outside both: 7
Intersection: 6
Only ET: 7
Only NDC: 10
B) 17/30
Step-by-step explanation:
Outside both: 7
Union: 30 - 7 = 23
Intersection: 13 + 16 - 23 = 6
Only ET: 13 - 6 = 7
Only NDC: 16 - 6 = 10
P(only one) = (7+10)/30
17/30
Y=2240+100x+70x
y=170x+2240
x represents the number of weeks
Multiply x by 100 to get the amount of money saved from his parents
Multiply x by 70 to represent 1/3 of his paycheck each week (210/3)=70
add 2240 because that is how much money there is to begin with in the account(this would be the y-intercept)
