Answer:
2000 envelopes
Step-by-step explanation:
Number of boxes bought by Mr. Turkowski at office supply store= 4 boxes
Number of envelopes in each box= 500 envelops
We have to find total number of envelopes in 4 boxes
Total number of envelopes in 4 boxes = Number of boxes × number of envelopes
Total number of envelopes in 4 boxes =4×500
Total number of envelopes in 4 boxes= 2000 envelopes
Hence, the correct answer is 2000 envelopes
