$6.84 divided by 18= .38 which means 38 cents per pen
$8.40 divided by 30= .28 which means 28 cents per pen
so $8.40 for 30 pens is a better deal than 18 pens for $6.84 by ten cents.

C
All Real Numbers, this is because it has infinitely MANY solutions.
Step-by-step explanation:
The answer is below
Step-by-step explanation:
Two triangles are said to be congruent if for the two triangles all the three sides are equal and all the three angles are equal to each other.
Given that ΔPQR is congruent to ΔSTU, hence all corresponding sides and corresponding angles are equal to each other.
∠P = ∠S = 59°
∠S + ∠T + ∠U = 180° (sum of angles in a triangle)
59 + 75 + ∠U = 180°
134 + ∠U = 180°
∠U = 46°
∠U = ∠R = 46°
∠Q = ∠T = 75°
Also, for the sides:
ST = PQ = 7 m
SU = PR = 8 m
Answer=30
20%=20/100=0.2
150*.20=30
