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
It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6.
