Lawrence has a total of 15 five dollar bills and ten dollar bills in his pocket. the value of these bills is $100.00. how many five dollar bills are in lawrence's
pocket?

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.
