Given the information below: (use normal time to calculate original path) a) which activity(s) should be crashed and what is the cost to reduce the project completion time from 22 to 21 days? b) which activity(s) should be crashed and what is the cost to reduce the project completion time from 21 to 20 days? c) which activity(s) should be crashed and what is the cost to reduce the project completion time from 20 to19 days? d) what is the total cost to reduce the project from the original normal completion time to 19 days? activity immediate predecessors normal time crash time normal cost crash cost a - 5 3 $3,000 $3,600 b - 6 4 $3,500 $4,300 c a 7 5 $3,300 $4,000 d b 5 4 $2,200 $2,400 e b 3 2 $1,700 $2,200 f d, e 5 3 $2,200 $3,600 g c, d 7 6 $1,900 $2,550 h f, g 3 2 $1,200 $1,750

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

answer: sine

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
