Hey there!
To start, you know the quantity of each bread Harry has bought:
1.6 pounds rye rolls
3.1 pounds hamburger buns
1.2 pounds English muffins
You also know the cost of each type for every pound of bread bought:
rye rolls-13 dollars
hamburger buns-14 dollars
English muffins-17 dollars
Now, to find the cost Harry spends in total, first find the cost of each amount of bread by multiplying the quantity bought with the unit price:
rye rolls: 1.6*13= $20.80
hamburger buns: 3.1*14= $43.40
English muffins: 1.2*17= $20.40
Now, add the costs together:
20.80+43.40+20.40=84.60
Therefore, Harry spends a total of $84.60
Hope this helps!
