Answer:

  $1000

Step-by-step explanation:

If we assume that the given average applies to April, May, and June expenses, then we can use the formula for average to find June's expenses.

  average expenses = (April +May +June)/3

  940.21 = (945.50 +875.13 +June)/3

  (3)(940.21) = 1820.63 +June

  2820.63 -1820.63 = June = 1000.00

Rob's expenses in June were $1000.00.
