denotes number of frosting flowers
Step-by-step explanation:
Let
denotes number of frosting flowers.
Amount charged by baker for each batch of cupcakes = $30
Amount charged for each frosting flower = $0.09
So,
Amount charged for
frosting flowers = 
Therefore,
Total cost of a batch of cupcakes with frosting flowers = 
Use Pythagorean theorem.
[tex]|ON|^2+|MN|^2=|OM|^2\\\\x^2+x^2=8^2\\\\2x^2=64\ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2=32\to x=\sqrt{32}\\\\x=\sqrt{16\cdot2}\\\\x=\sqrt{16}\cdot\sqrt2\\\\\boxed{x=4\sqrt2}
Answer: |MN| = 4√2.
1 pound = 16 ounces
20 pounds = 320 ounces
320 ounces + 7 ounces = 327 ounces
