Answer 1

Answer: 12 small candles and 16 large candles.

Step-by-step explanation:

Notice that an small candle costs $4 and a large candle costs $6.

Let be "s" the number of small candles you sold and "l" the number of large candles you sold.

Set up a System of equations:

$\left \{ {{4s+6l=144} \atop {s+l=28}} \right.$

Use the Elimination Method to solve it:

- Multiply the second equation by -4.

- Add the equations.

- Solve for "l".

Then:

$\left \{ {{4s+6l=144} \atop {-4s-4l=-112}} \right.\\.......................\\2l=32\\\\l=16$

- Substitute the value of "l" into the second equation and solve for "s":

$s+16=28\\\\s=12$
