Nezavi [6.7K]

9514 1404 393

Answer:

  62.5 oz of 100%

Step-by-step explanation:

Let p represent the number of ounces of pure syrup. Then (100-p) is the number of ounces of 60% syrup. The amount of maple syrup in the desired mix is ...

  p +0.60(100 -p) = 0.85(100)

  0.40p +60 = 85 . . . . . . . . . . . simplify

  0.40p = 25 . . . . . . . . . . subtract 60

  p = 62.5 . . . . . . . . . divide by 0.4

62.5 ounces of pure syrup should be mixed with the diluted syrup to make 100 ounces of 85% maple syrup.

_____

The other 37.5 ounces will be 60% syrup.

Jerod is making candles from beeswax. He has 132.72 ounces of beeswax. If each candle uses 8.4 ounces of beeswax, how many candl
Valentin [98]

Answer:

15 candles and 6.72 ounces left over.

Step-by-step explanation:

Jerod has the amount of beeswax = 132.72 ounces

Jerod is making candles from beeswax.

one candle uses the amount of beeswax = 8.4 ounces

Total candles can be made from total beeswax = \frac{132.72}{8.4}

                                                                                = 15.8

With 132.72 ounces wax 15 candles were made.

In order to calculate the left over wax we calculate the amount is used in 15 candles

= 8.4 × 15 = 126 ounces

Left over wax = 132.72 - 126 =  6.72 ounces

Therefore, 15 candles can be made and 6.72 ounces wax would be left over.
