Answer: 9.25 lbs
Step-by-step explanation:
The described situation can be modelled in the following equation:
[tex]Total=(5 lbs+8 oz)+(4 lbs+15 oz)[/tex]
But firstly, we have to convert the amounts in ounces to pounds in order to work with the same units, taking into account [tex]1 oz=0.0625 lbs[/tex]:
[tex]8 oz \frac{0.0625 lbs}{1 oz}=0.3125 lbs[/tex]
[tex]15 oz \frac{0.0625 lbs}{1 oz}=0.937 lbs[/tex]
Then:
[tex]Total=(5 lbs+0.3125 lbs)+(4 lbs+15 oz+0.937 lbs)[/tex]
[tex]Total=9.25 lbs[/tex] This is the totall Amy bought
