Five-crown 6091

The customer paid the amount of CZK 3,200 with the same 100-crown, two-crown and five-crown banknotes. How many banknotes did he use to pay the amount if he paid precisely the amount?

Correct answer:

a =  89.7196

Step-by-step explanation:

3200=100b+2b+5b 107b=3200 b=3200/107=29.906542  a=3 b=3 29.9065=89.7196

3200 = 100b+2b+5b


3200 = 100·b+2·b+5·b

107b = 3200


b = 3200/107 = 29.90654206

b = 3200/107 ≈ 29.906542
