Final answer:
The art club's profit is $0.
Step-by-step explanation:
To calculate the club's profit, we need to determine the total income from selling the candles and subtract the total cost of purchasing the candles.
The total income from selling the large candles can be found by multiplying the quantity sold (42) by the price per candle ($5), which is equal to $210.
The total income from selling the small candles can be found by multiplying the quantity sold (56) by the price per candle ($3), which is equal to $168.
Therefore, the club's total income is $210 + $168 = $378.
The total cost of purchasing the candles can be found by multiplying the quantity of large candles (42) by the cost per candle ($5), which is equal to $210.
The total cost of purchasing the small candles can be found by multiplying the quantity of small candles (56) by the cost per candle ($3), which is equal to $168.
Therefore, the club's total cost is $210 + $168 = $378.
To find the profit, subtract the total cost from the total income: $378 - $378 = $0.
Therefore, the club's profit is $0.
