Machine A has a fixed daily cost of $20 and a variable cost of $1.00 per item produced. Machine B has a fixed daily cost of $10 and a variable cost of $1.50 per item produced.
(b) What is the total daily cost per machine for this number of items?

step-by-step explanation:

times by times

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
