<em>Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories.
</em>
<em>If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?</em>
Here is my answer
Let x is number of shirts
Person COST
ERIN 12x+18
DAN 16x+10
Equally Billed 12x+18=16x+10 <=> x = 2
so each of them buy 2 shirts
Hello!
The answer is B

Answer:
Step-by-step explanation:
Suppose that the side length is s. Imagine that one side is level. Draw a vertical line through the top vertex perpendicular to the base (level side). Label this vertical line "h." Then h and s are related as follows:
√3 h
sin 60 degrees = ------- = --------
2 s
s√3
and so h = the height of the triangle = -----------
2
The area of this triangle is (1/2)(base)(height), which here is:
(1/2)(s/2)( s√3 /2), or
(s^2)√3
A = ---------------
8
