Step-by-step explanation:
CP of all his books = $200
profit = 10%
SP = CP ( 100 + gain% / 100 )
after inserting the values we got,
→ 200 ( 110/100 )
→ 2 × 110
→ 220
therefore, Selling Price of all the books are $220.
hope this answer helps you dear...take care! and may u have a great day ahead!

Answer:
(483.981 ; 504.019)
Step-by-step explanation:
Given :
σ = 100
Sample size, n = 661
xbar = 494
We use the Z distribution since we are working with the population standard deviation ;
C.I = xbar ± (Zcritical * σ/√n)
Zcritical at 99% = 2.576
C.I = 494 ± (2.576 * 100/√661)
C.I = 494 ± 10.019
Lower boundary = (494−10.019) = 483.981
Upper boundary = (494+10.019) = 504.019
C.I = (483.981 ; 504.019)
