Using cos addition formula:
use x for theta
cos(x+π/6)=cosx*cos(π/6)-sinx*sin(π/6)
sinx=1/4
cosx=√15/4
cos(π/6)=√3/2
sin(π/6)=1/2
cos(x+π/6)=(√15/4*√3/2)-(1/4*1/2)
cos(x+π/6)=(√45/8)-(1/8 )
cos(x+π/6)=(√45-1)/8)

Answer:
.85
Step-by-step explanation:
Price she would have to pay =
(Price on Tag (Original Price)) - (Cost Discount) =
(Price on Tag) - (15%)(Price on Tag) =
(100%)(Price on Tag) - (15%)(Price on Tag) =
(100% - 15%)(Price on Tag) =
85% * (Price on Tag) =
.85 * (Price on Tag),
so .85 is the answer.
