Another MathXl i need help please im suffering

If you would like to find the step where Betty first made an error, you can do this using the following steps:

Step 1: ($52.65 * 5 weeks + $46.25 - $16.25) * 1/6 = (52.65 * 5 + 46.25 - 16.25) * 1/6
Step 2: ($263.25 + $46.25 - $16.25) * 1/6 = (263.25 + 46.25 - 16.25) * 1/6
Step 3: $293.25 * 1/6 = 293.25 * 1/6
Step 4 : $48.875 = $48.88

Betty first made an error in step 4 (she multiplied 293.25 by 6 and not by 1/6).
