Answer: She needed [tex]1\frac{1}{2}\text{ pounds of blueberries}[/tex] to make a cup of jam .
Step-by-step explanation:
Since we have given that
Sarah used [tex]\frac{3}{4}[/tex] pound of blueberries to make [tex]\frac{1}{2}[/tex] cup of jam.
As we need to find the number of pounds of blueberries she would need to make a cup of jam.
So, we will use "Unitary Method":
[tex]\text{For }\frac{1}{2}\text{ cup of jam},\\\\\text{ she need }\frac{3}{4}\text{ pound of blueberries }\\\\\text{ For 1 cup of jam}.\\\\\text{She need }=\frac{3}{4}\times 2=\frac{3}{2}=1\frac{1}{2}\text{ pounds of blueberries }[/tex]
Hence, She needed [tex]1\frac{1}{2}\text{ pounds of blueberries}[/tex] to make a cup of jam .
