Step 2.

Step-by-step explanation:

I may be wrong, but I think the wrong steps is step 2 because he already did this in step 1.

Camryn Fernandez · Answer 2

It would be step 1.

Step-by-step explanation:

I know this because in the 22.75 + 3 he was tyring to calculate how much he had made just from delivering.

The extra 32.75 was how much he had saved from chores.

He didn't make 22.75 + 3 from delivering, he made 22.75 a week meaning he should have multiplied, not divide.

I think it is step 1.
