Mrs Gonzalez bought centerpieces to put on each table at a graduation party. She spent $31.50. There are 8 tables each requiring either a candle or vase. Candles cost $3 and vases cost $4.25. How many of each type did she buy?

Respuesta :

Answer:

2 candles, 6 vases

Step-by-step explanation:

Assume: c = # of candles, v = # of vases

Systems: c + v = 8, 3c + 4.25v = 31.50

Multiply first equation by -3, then subtract equations: 1.25v = 7.5

v = 6

Substitute: c + 6 = 8, c = 2
