You sell your bicycle to your friend for 65$ your friend gives you x five dollar bills and y ten dollar bills. There are a total
jeka94

Answer:

There are 5 five dollar bills and 4 ten dollar bills.

Step-by-step explanation:

Given:

Selling price of bicycle =\$65.

The friend gave x five dollar bills and y ten dollar bills.

Total number of bills =9.

To find: Number of five dollar bills and ten dollar bills the friend gave.

Solution:

The friend gave x five dollar bills and y ten dollar bills and the friend gave 9bills in all.

So, x+y=9.

\Rightarrow x=9-y   ...(i)

Selling price of bicycle =\$65.

So, 5x+10y=65...(ii)

Putting the value of x from equation (i) in equation (ii).

\Rightarrow 5(9-y)+10y=65

\Rightarrow 45-5y+10y=65

\Rightarrow 45+5y=65

\Rightarrow 5y=65-45

\Rightarrow 5y=20

\Rightarrow y=\frac{20}{5}

\Rightarrow y=4

Now, putting the value of y in equation (i).

\Rightarrow x=9-4

\Rightarrow x=5

Hence, there are 5 five dollar bills and 4 ten dollar bills.
