the cost of labor varies jointly as the number of workers and the number of days that they work. if it costs $1450 to have 16 people work for 7 days, how much will it cost to have 20 people work for 13 days?a. $3367
b. $3380
c. $3385
d. $3388
e. $3395Since C(p,d) = p*d*kwhere:
C(p,d) = total cost
p=people
d=days
k=cost constant with units of $/(p d)Solving for k:
$1450.00 = 16*7*k
k=1450/(16*7)
k=$12.95Solving for C(p,d) of problem:
C(p,d)= 20*13*$12.95
C(p,d)=$3367.00So a. is correct.Good luck with your assignment!
