$2.50

Step-by-step explanation:

$8 x 1.75 = $14.00 Price with the 75% markup

$14.00 (25%) = $3.50 is the 25% discount at the end of year.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
