Answer:
16.25;
g(f(x)) ;
76 ;
f(g(x))
Explanation:
For 15 off
f(x) = x - 15
For 35% off
g(x) = (1 - 0.35)x = 0.65x
g(x) = 0.65x
A.)
For the $15 off coupon :
f(x) = x - 15
f(x) 40 - 15 = 25
For the 35% coupon :
g(x) = (1-0.35)x
g(x) = 0.65(25)
g(x) = 16.25
B.)
Applying $15 off first, then 35%
Here, g is a function of f(x)
g(f(x))
Here g(x) takes in the result of f(x) ;
For the $140 off coupon :
f(x) = x - 15
f(140) = 140 - 15 = 125
For the 35% coupon :
g(125) = (1-0.35)x
g(124) = 0.65(125) = $81.25
C.)
x = 140
g(x) = 0.65x
g(140) = 0.65(140)
g(140) = 91
f(x) = x - 15
f(91) = 91 - 15
f(91) = 76
D.)
Here, F is a function of g(x)
f(g(x))
f(x) = (0.65*140) - 15
Answer:
D. today's dollars; purchasing power
The nominal value of anything is it's current price or the dollar amount someone is paying for it. For eg if the price of a kg of rice is $3, its nominal value is also $3. The real value is expressed in terms of purchasing power which means that the amount of goods and services that you can purchase from a particular amount of money today compared to a base year in the past. So for example if the base year is 5 years ago and the price of a kg of rice was $1.5, the real value of $3 would be 2 kgs of rice, where as currently if the price of a kg of rice is $3 then the real value of $3 is 1 kg of rice. As purchasing power decreases the real value of money decreases.
