2. Rhett put up ten posters in his neighborhood and handed out fliers at a local grocery store each with a photo of his lost puppy. Rhett paid $2 per poster and $0.20 per flier to print. If x represents the number of fliers he handed out at the grocery store, which of the following equations can be used to find how much it cost Rhett to search for his lost puppy? y = 0.20x + 20 y = 2x + 0.20 y = 0.20x + 2 y = 20x + 0.20

The prompt stated that there were ten posters already posted and each cost $2. Now, Rhett is handing out fliers (our current rate) at 20 cents per flier. So fliers are our independent variable x: \[y = 0.20x + 2\left( 10 \right)\] which simplifies to: \[y = 0.2x + 20\] and this equation will give us Rhett's total cost.

but its 2. Rhett put up ten posters in his neighborhood and handed out fliers at a local grocery store each with a photo of his lost puppy. Rhett paid $2 per poster and $0.20 per flier to print.

y = 0.20x + 20

\[0.2 = 0.20\] The former is just a simplified version of the latter number. In other words, both of those equations mean the same. Note: The extra zero is merely a stylistic choice to signify monetary amounts.
