Answer:
Each small candleholder holds 3 candles, and each large one holds 5 candles.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of candles that a small candleholder holds.
y is the number of candles that a large candleholder holds.
24 small candle holders and 3 large candle holders, using a total of 87 candles.
This means that
Simplifying by 3
14 small candle holders and 7 large candle holders, for a total of 77 candles.
This means that
Simplifying by 7
Since
Each small candleholder holds 3 candles, and each large one holds 5 candles.
