Roll needs to make a soil mixture consisting of 2/5 sand, 2/5 clay, and 1/5 peat moss. If he uses 75 pounds of sand, how many total pounds of soil will he have when he adds clay and peat moss to the sand to make the correct mixture?

Answer :

Answer:

187.5 pounds

Step-by-step explanation:

Fraction of sand = 2/5

Fraction of clay = 2/5

Fraction of peat = 1/5

Pounds of sand = 75

The total pounds of soil required to make Correct mixture : let that be x

Hence,

Using the sand Fraction and pounds which we know :

2/5 of x = 75

2x / 5 = 75

Cross multiply :

2x = 75 * 5

2x = 375

x = 375 / 2

x = 187.5

Required pond of sand =187.5 pounds
