Question

Bentano spends $170 to order 30 pounds of nuts from an online company. The company charges $3.50 per pound for peanuts and $7.50 per pound for almonds. It also charges a flat fee of $13 for shipping and handling.Which equation can be used to find p, the number of pounds of peanuts Bentano buys?3.5p+7.5(p−30)−13=1703.5p+7.5(30−p)−13=1703.5p+7.5(p−30)+13=1703.5p+7.5(30−p)+13=170

Answer 1

4th option: 3.5p + 7.5(30 - p) + 13 = 170

Explanation:

The total amount of nuts is the sum of peanuts and almonds.

Therefore, let the number of peanuts be p and the number of almonds be the remainder, that is, 30 - p.

The total expense will be the cost of peanuts, almonds and shipping and handling.

Taking the above into account, we would have:

3.5p + 7.5(30 - p) + 13 = 170

And this corresponds to the 4th option
