1. A set of weights includes a 5 lb barbell and 5 pairs of weight plates. Each pair of plates weight 30 lb. If x pairs of plates are added to the barbell,
the total weight of the barbell and plates in pounds can be represented by
f(x) = 30x + 5.
What is the range of the function for this situation?
A (0,1,2,3,4,5)
B (5,35, 65, 95, 125, 155)
C (0,1,3,5)
D (5, 65, 125, 155)

12.5 feet

step-by-step explanation:

$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

the answer is  

a.
