Question

Paulette has $140 in five dollar bills and $10 bills the number of $10 bills is one less than twice the number of five dollar bills how many of each does she have

Answer 1

Paulette has 6 five dollar bills and 11 ten dollar bills.

Explanation:

28 five dollar bills is equal to $140

14 ten dollar bills is $140

The total value of the five dollar bills is given by multiplying the number of bills by $5, so it is 5x.

Similarly, the total value of the ten dollar bills is given by multiplying the number of bills by $10, so it is 10(2x - 1) = 20x - 10.

According to the problem, the total amount of money Paulette has is $140. Therefore, we can set up the equation:

5x + (20x - 10) = 140

Simplifying the equation:

5x + 20x - 10 = 140

25x - 10 = 140

25x = 140 + 10

25x = 150

x = 150 / 25

x = 6

So Paulette has 6 five dollar bills and (2 * 6 - 1) = 11 ten dollar bills.
