The cookie recipe needs 3/4 cup of sugar and 1/8 cups of butter. Alice puts in 1 cup of butter by mistake. How much sugar will be needed?

6 cups of sugar

Step-by-step explanation:

a) how do you even mess up a cookie recipe that bad, she’s going to have 7 batches more than she wanted (ignore this)

and b) Alice put in 8 times as much butter more than she should’ve (1/8x8=1 cup), so multiply the amount of sugar by 8.

3/4x8=24/4, or 6 cups of sugar

whatever you can spend with $11.53 or under.

step-by-step explanation:
