Question

Which equation to represent the following sentence: Two pounds of nuts costs

x dollars per pound and four pounds of chocolate costs $3 per pound combining to a total amount of $20.





2x+60=4



2(x+4)=20



2x+12=20



2(x+12)=20

Answer 1

(c) 2x+12=20

Explanation:

You want the equation that represents, "Two pounds of nuts costs x dollars per pound and four pounds of chocolate costs $3 per pound for a total amount of $20."

Extended cost

When computing a total bill, the amount is the sum of the products of cost per item and the number of items at that cost.

Here, the total bill is 2 pounds at x dollars per pound (2x), and 4 pounds at 3 dollars per pound (4(3)) = 12. The sum of these products is ...

2x +12 = 20
