Answer:$18.75
Step-by-step explanation:

Eric's share is $18.75.
Answer:
see below
Step-by-step explanation:
The component form of the polar coordinate pair (r, θ) is ...
(r, θ) ⇔ (r·cos(θ), r·sin(θ))
Then your point (2, 60°) translates to ...
(2, 60°) ⇔ (2·cos(60°), 2·sin(60°)) = (2(1/2), 2(√3)/2) = (1, √3)
X - y = 28 (difference between the two numbers)
and
x - 8 = 2y (8 less than twice the smaller number)
From the first . . . x = 28 + y
28 + y - 8 = 2y
20 = 2y - y
20 = y
x - 20 = 28
x = 28 + 20 = 48
