Check the picture below.

we know the lines are angle bisectors, so the line makes twin angles, so the line FP is making twin angles, we also know the angle FZP and the angle FYP are right-angles, as well as FP is a common hypotenuse to two right triangles, thus by the HA postulate for right triangles, triangle FPZ and triangle FPY are both congruent, so their sides are also congruents, thus PY = PZ.

13.) Which of these is a better deal, on a per ounce basis?

Gala2k [10]

Using proportions, it is found that the better deal, on a per ounce basis, is given by:

A a 30 oz. box of Tasty Wheats for $4.20

<h3>Proportion</h3>

To find the better deal, we use <em>proportions </em>to find the cost per ounce, that is, dividing the cost per the amount of ounces. The <em>better deal </em>is the one with the smaller cost per ounce.

For each option, the costs per ounce are given by:
