Answer:
you pay $69.74
Step-by-step explanation:
total cost without coupon: 15+65+14 = 94
apply the 30% discount ⇒ 94 × .30 = 28.20
subtract the savings ⇒ 94.00 - 28.20
total, after coupon, before tax ⇒ 65.80
apply 6% tax to 65.80 ⇒ 65.8 × .06 ⇒ 3.94
add tax to cost after coupon ⇒ 65.80 + 3.94
12
f(14)= f (3 + 11)
= f(3) = 12
Therefore the value of f(14) is 12.
