Question

One last question. A recipe that makes 18 cookies calls for 3/4 cup of sugar.How much sugar is needed to make 2 dozen cookies using this recipe?

Answer 1

this is called direct variation:

18 is to 3/4 as 24 is to x cups, or\[\frac{18}{.75}=\frac{24}{x}\]cross-multiply\[18x=.75*24\]or\[x=\frac{.75*18}{18}=1\]
