Answer:
David make his first error at Step 3
Step-by-step explanation:
We need to determine the error David made when finding the product of (-2.5)(-8.3)
He did the following steps
Step 1: (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2: = (–8.3)(–2) + (–8.3)(–0.5)
Step 3: = (–16.6) + (–4.15)
Step 4: = –20.75
David made a mistake in Step 3
When we multiply (-1) with (-1) we get + instead of - sign. The correct step 3 would be:
Step 3: =(16.6)(4.15)
Step 4: =20.75
So, David make his first error at Step 3
