A motel clerk counts his $10 bills and $20 bills at the end of the day. He finds that he has a total of 150 bills, and that those 150 bills have a total value of $2,000. How many $10 bills and $20 bills does the motel clerk have? Translate the problem into 2 equations.

Let the x be the number of $10 bills and y be the number of $20 bills.

100 $10 bills and

50 $20 bills

Step-by-step explanation:

Given

Required

Determine the number of $10 and $20 bills

.

This implies that:

This implies that:

So, the equations are:

Make x the subject in the first equation

Substitute 150 - y for x in the second

Recall that:

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
