David made an error when determining the product of (–2.5)(–8.3).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: = –20.75In which step did David make his first error?

Step 1 correctly switches the order of the factors, and Step 2 correctly breaks −2.5 into −2 and −0.5. In Step 3, (−8.3)(−2) equals 16.6 and (−8.3)(−0.5) equals 4.15, since multiplying two negative numbers gives a positive product. Therefore, David’s first error is Step 3.
