Meat Lover’s Special

12-inch round pizza…….……….$15.00
18-inch round pizza……………..$19.00
Which pizza listed on the menu provides the best value? Write a few sentences
that explain your reasoning

18 inch round pizza

Step-by-step explanation:

you need to find the price per inch and whichever pizza costs the least per inch, thats your best deal!

so for the 9- inch round you would divide $10.50 by how many inches there are which is 9 so each inch costs aproximately $1.16

for the 12- inch round, you will divide the price of $15 by the 12 inches of pizza which will equal out to $1.25

for the 18 inch round pizza, you will divide the price of $19 by the 18 inches which will equal out to about $1.05

so, going off of the price per inch of pizza, the 18 inch round pizza is giving you the best deal.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
