Question
A gardener buys two kinds of fertilizer. Fertilizer A contains filler materials by weight and Fertilizer B contains filler materials by weight. Together, the fertilizers bought by the gardener contain a total of 240 pounds of filler materials. Which equation models this relationship, where x is the number of pounds of Fertilizer A and y is the number of pounds of Fertilizer B?
Hint:
Hint:
- Percentage, a relative value indicating hundredth parts of any quantity.
- Equation with two variable represents the relation between then, means how one variable change with change in another variable.
The correct answer is:
Explanation:
- We have given Fertilizer A contains filler materials by weight and Fertilizer B contains filler materials by weight. Together, the fertilizers bought by the gardener contain a total of pounds of filler materials.
- We have to find the equation that relates the number of pounds of fertilizer A and fertilizer B.
- We will first calculate the number of pounds of filler material in fertilizer A and fertilizer B separately and then apply the condition and then make the equation.
Step 1 of 1:
The number of pounds of Fertilizer A is x and it contains filler material
So,
Now, the number of pounds of Fertilizer B is y and it contains filler material
So,
And it is given that the total number of pounds of filler materials is 240.
So,
Hence, Option (B) is correct.
