Question

A mixture of 8% olive oil and 92% water is to be used to make a gravy. How much pure olive oil should be added to 46 ounces of water to make the micture?

Answer 1

Answer:

4 ounces

Step-by-step explanation:

Given that every mixture of gravy must contain 8% olive oil and 92% of water, and we are given 46 ounces of water.

therefore if

92% = 46 ounces

8% = x ounces

where x is the mass of olive oil in ounces to be added to water to form the mixture.

when we cross multiplying we will have

92 * x = 8 * 46

92x = 368

dividing both side by 92

x = 368/92 = 4 ounces
