Answer:
50 grams.
Explanation:
Let x be the amount of cheese recipe requires.
We have been given that Ann increased the quantities of all the ingredients in a recipe by 60%. She used 80 grams of cheese. We are asked to find the amount of cheese the recipe requires.
Since Ann increased the quantity of cheese by 60%, so the amount of cheese used by Ann would be x plus 60% of x. We can represent this information in an equation as:





Therefore, the recipe requires 50 grams of cheese.
