A baker uses 2 1/3 cups of cookie dough and 1/4 cup of chocolate chips to make 10 cookies. If the baker has 3 cups of chocolate chips, how much dough will he need

Answer: he will need 28 cups of dough for 3 cups of chocolate.

Step-by-step explanation:

The baker uses 2 1/3 cups of cookie dough and 1/4 cup of chocolate chips to make 10 cookies. Converting 2 1/3 cups of cookie dough into improper fraction, it becomes 7/3 cups of cookie dough.

It means that for every 1/4 cup of chocolate, 7/3 cups of cookie dough is needed.

Let x represent the amount of cookie dough needed for 3 cups of chocolate chips.

If 7/3 dough = 1/4 cup of chocolate

x dough = 3 cups of chocolate

x * 1/4 = 7/3 * 3

x/4 = 7

x = 7*4 = 28 cups of dough
