Answer:
There are 10 five dollars bills in Lawrence's pocket.
Step-by-step explanation:
Given,
Total bills = 15,
Let x be the number of five dollar bills,
⇒ The number of ten dollars bill = 15 - x
Thus, the total amount = 5x + 10(15-x)
According to the question,
5x + 10(15-x) = 100
⇒ 5x + 150 - 10x = 100
⇒ - 5x + 150 = 100
⇒ -5x = 100 - 150
⇒ -5x = -50
⇒ x = 10
Hence, there are 10 five dollars bills in Lawrence's pocket.
