b. 16 and 39
c. 66 and 77
d. 90 and 891 user: are 30 and 138 relatively prime numbers

B.16 and 39

Step-by-step explanation:

A number is said to be a relative prime numbers if the only positive integer (factor) that divides both of them is 1.

16=2*2*2*2

39=3*13

It is noticed that there’s no common factor in the example.

The only common factor is one. This makes B correct.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
