A bank teller has 47 $20 and $5 bills in her cash drawer. The value of the bills is $490. How many $20 bills are
lina2011 [118]

Answer:

x = 17 $20 bills

y = 30 $5 bills

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Multivariable Systems

Step-by-step explanation:

<u>Step 1: Define variables</u>

x = # of $20 bills

y = # of $5 bills

<u>Step 2: Set up systems of equations</u>

<u />\left \{ {{x+y=47} \atop {20x+5y=490}} \right.<u />

<u />

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Rewrite:                                        \left \{ {{y=47-x} \atop {20x+5y=490}} \right.
  2. Substitute:                                     20x+5(47-x)=490
  3. Distribute 5:                                   20x+235-5x=490
  4. Combine like terms:                     15x+235=490
  5. Subtract 235 on both sides:        15x=255
  6. Divide both sides by 15:               x=17

By solving for <em>x</em>, we now know that we have 17 $20 bills.

<u>Step 4: Solve for </u><em><u>y</u></em>

  1. Define:                                        x + y = 47
  2. Substitute:                                  17 + y = 47
  3. Subtract 17 on both sides:         y = 30

Now we know that we have 30 $5 bills.
