Question

A bag of trail mix weighs 2 lb. By weight, 18% of the trail mix is oats.

Write a percent equation that can be used to find the weight of the oats in the trail mix.
a) 18% = x% of 2 lb
b) 2 lb = 18% of x%
c) 2 lb = x% of 18%
d) x% = 18% of 2 lb

Answer 1

The correct percent equation to determine the weight of the oats in the trail mix is 18% = x% of 2 lb. By converting the percentage to a decimal and multiplying, we find that the oats weigh 0.36 lb.

Step-by-step explanation:

To find the weight of the oats in terms of percent equation, we need to express the weight of the oats (which we will call 'x') as a percentage of the total weight of the trail mix. The total weight of the trail mix is given as 2 lb, and the percentage of the mix that is oats is 18%. Therefore, the correct percent equation to find the weight of the oats in the trail mix is option a) 18% = x% of 2 lb.

Percent equation: 18% = x% of 2 lb

To solve for 'x', we would convert the percentage to a decimal and multiply it by the weight of the trail mix:

x = 0.18 × 2 lb

x = 0.36 lb

So, the weight of the oats is 0.36 lb.
