Answer:
Margaret use [tex]4\frac{3}{8}[/tex] teaspoons of vanilla .
Step-by-step explanation:
Vanilla required for 12 cupcakes = [tex]1 \frac{3}{4} = \frac{7}{4}[/tex]
Vanilla required for 1 cupcakes = [tex]\frac{\frac{7}{4}}{12}[/tex]
= [tex]\frac{7}{48}[/tex]
Vanilla required for 30 cupcakes = [tex]\frac{7}{48} \times 30[/tex]
= [tex]\frac{35}{8}[/tex]
= [tex]4\frac{3}{8}[/tex]
Hence Margaret use [tex]4\frac{3}{8}[/tex] teaspoons of vanilla .
