Which equations model exponential decay?
select each correct answer.

a. y=0.55(0.91)^x

b. y=4.2(1.25)^x

c. y=0.25(2)^x

d. y=2(0.20)^x

probably the last option

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
