Answer 1

Answer:

Step 2 is incoreect.

Step-by-step explanation:

Cost of Naty's dress = $24.95

Cost of Naty's skirt = $14.95

The sales clerk said the total cost including 9.5% sale tax was $49.40.

Step 1 is correct i.e. 24.95 + 14.95 = 39.90

In step 2, he added 39.90 and 9.5. This is the wrong step. He directly added 9.5 but he have to add 9.5% i.e. 0.095.

Cost = 39.90 + 0.095

C = $39.995

Step 2 is incorrect.
