The number of small and large candles.
Answer to Problem 28E
The numbers of large and small candles are 16 and 12 respectively
Explanation of Solution
Given:
Total selling price is $144.
Total number of candles is 28.
Cost of large candle is $6.
Cost of small candle is $4.
Calculation:
Consider the number of large and small candles as x and y respectively.
The equation by its selling price is calculated as follows:
The equation by total number of candles is calculated as follows:
Solve the equation (1) and (2) by elimination method.
Multiply the equation (2) by 6 and subtract from equation (1) as follows:
Substitute value of y in equation (2) as follows:
Thus, the numbers of large and small candles are 16 and 12 respectively
