Answer:
12 Small, 16 Large
Step-by-step explanation:
When you do the math of getting 16 large candles and 12 small candles with respects to the price. You get the math of:
(6×16) + (4×12)
96 + 48
144
16 and 12 will make 28 which proves to be correct as 28 candles were sold
There is a simple algebraic solution to this; a system of equations!
x = small candles and y = large candles
4x + 6y = 144
x + y = 28
Now there are two ways to solve this; substitution and elimination.
Let’s use substitution for practice with the distributive property...
4x + 6y = 144
y = -x + 28
Put the second equation into the first...
4x + 6(-x + 28) = 144
4x - 6x + 168 = 144
-2x + 168 = 144
-2x = -24
x = 12
Plug this into one of the original equations....
12 + y = 28
y = 16
And there you have it! You sold 12 small candles and 16 large candles.
