morpeh [17]

A store has two different coupons that customers can use. One coupon gives the customer $15 off their purchase, and the other co
andrey2020 [161]

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
