Ann increased the quantities of all ingredients in a recipe by 60%.she used 80 g of cheese how many much cheese does the recipe require

The way the problem is stated, it is not very clear.
I assume the original recipe uses 80 g of cheese, and she increased it by 60%.

The increase is 60%, so we need to calculate 60% of 80 g.

60% of 80 g = 60% * 80 g = 0.60 * 80 g = 48 g

The recipe requires 48 g more cheese.

The answer is $9.90 with rounding to the nearest tenth
