Anna buys groceries for her family. hamburger meat is $3.38 per pound sweet potatoes are$0.79. each and hamburger rolls are $2.30a bag. if anna buys 3 pounds of meat 5 sweet potatoes and 1 bag of hamburger rolls what will she pay in all for the groceries

2.30 x 1 = 2.30 for the hamburger rolls
3.38 x 3 = 10.14 for the hamburger meat
.79 x 5 = 3.95 for the sweet potatoes

3.95 + 2.30 + 10.14 = 16.39$ is her total.

To further explain this, and/or to find answers to similar problems like this, you take the amount per pound or whatever unit of measurement (let’s say this variable is Z) and then you take the amount that they are getting per said unit ( let’s say Y) thus an equation that can be used to find problems like this is Z x Y.
