Question

Brix has 4,000 in denominations of 500 and 100. he has a total of 20 bills. How many of each bill does he have?

Answer 1

Answer:

Brix has 5 bills of 500 denomination and 15 bills of 100 denomination. Please mark me as brainliest.

Step-by-step explanation:

Let the number of 500 bills be x and number of 100 bills be y

x + y = 20 [Given]

y = 20 - x    ....1

500x + 100y = 4000  [Given]

100(5x + y) = 100(40)

5x + y = 40

5x + 20 - x = 40   [from 1]

4x + 20 = 40

4x = 40 - 20

4x = 20

x = 5

y = 20 - x = 20 - 5 = 15
