Phin bought a new ski helmet. The helmet was $49.99. It was on sale for 10% off. Find the final cost including CT tax. (CT tax is 6.35%) Round to the nearest penny if possible. Which is the correct

a. $47.84
b. $47.85
c. $51.34
d. $44.99

47.85

Step-by-step explanation:

49.99 x .10 = 4.99

49.99 - 4.99 = 45

45 x 0.0635 = 2.85

45 + 2.85 = 47.85

a) $47.84

Step-by-step explanation:

Answer is a) $47.84

45.45 x 1.10 = 49.99 then 49.99 x 1.0635 = 53.16 then 53.16 x 0.10 = 5.316 53.16-5.316 = 47.84

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
