To solve the equation 5x + 7.50 = 27.50 for x, we can follow these steps:
1. Subtract 7.50 from both sides to isolate the term with x:
5x + 7.50 - 7.50 = 27.50 - 7.50
5x = 20
2. Divide both sides by 5 to solve for x:
5x/5 = 20/5
x = 4
Therefore, the cost of one candle is $4.
The total cost of a candle holder and 5 candles is $27.50. The candleholder cost $7.50. Use the equation 5x + 7.50 = 27.50 to find x, the cost of one candle.
