goldfiish [28.3K]

Answer:$55,000

Step-by-step explanation: If you’re are worried about the amount of computers don’t because that is unnecessary.they didn't sell any computers this month or it would have been mentioned in the problem. I decided to make the sum of phones they sold 100 because half of 100 is 50. So they sold 100 phones and 50 tablets. I did 50 x 300= 15,000 because 300 is the price of 1 tablet. Then I did 100 x 400=40,000 because 400 is the price of 1 phone. Then I added the sums together (15,000+40,000=55,000).
