n(A∪B)=n(A)+n(B)−n(A∪B)=50+60−40=70
n(AΔB)=n(A∪B)−n(A∩B)
⇒70−40=30.
(128)/(360) = (32)/(total people)
solve for (total people)...
(128)(total people) = (32)(360)
total people = (32)(360)/(128) = 90 people total
Answer: $2000 + 0.08s ≥ $2500
Step-by-step explanation:
The expression that will be used to calculate the earnings of Liz will be:
= b + (c × s)
Where:
b = base salary = $2,000
c = commission rate = 8% = 8/100 = 0.08
s = the sales that the commission rate will be applied against.
The inequality to find amounts of sales that will meet Liz goal will be:
= b + (c × s)
= $2000 + (0.08 × s) ≥ $2500
= $2000 + 0.08s ≥ $2500
About 36000 because if u multiply 3000 the price of the automobile by number of payments 12 you get 36000
