Question

Fertilizer concentrate for grass is mixed with water to spray on yards. The fertilizer spray is made using a ratio of 1 part fertilizer concentrate and 6 parts water. How much fertilizer concentrate is needed, in ounces, to produce 4,200 ounces of spray?

Option a: 700 ounces
Option b: 600 ounces
Option c: 800 ounces
Option d: 500 ounces

Answer 1

To produce 4,200 ounces of fertilizer spray made with a ratio of 1 part concentrate to 6 parts water, you will need 700 ounces of fertilizer concentrate.

Step-by-step explanation:

To make the fertilizer spray, the ratio of fertilizer concentrate to water is 1:6. This means that for every 1 part of fertilizer concentrate, you need 6 parts of water. To find out how much fertilizer concentrate is needed to produce 4,200 ounces of spray, we can set up a proportion:

1 part fertilizer concentrate / 6 parts water = x ounces fertilizer concentrate / 4,200 ounces spray

Cross-multiplying, we get:

1 * 4,200 = 6 * x

Simplifying the equation:

4,200 = 6x

Dividing both sides by 6:

x = 700

Therefore, 700 ounces of fertilizer concentrate is needed to produce 4,200 ounces of spray.
