Question

Joe buys candy that costs $7 per pound. He will spend at least $56 on candy. What are the possible numbers of pounds he will buy?

Answer 1

Answer:

8 pounds(lbs)

Step-by-step explanation:

If a candy costs $7 per pound, $56 divided by $7 will equal 8 pounds.

Answer 2

Answer:

8 ≤ x pounds

Step-by-step explanation:

I will be using * as a symbol for multiplication.

We can create an inequality for this question.

x will represent the amount of pounds that he may buy.

56 ≤ 7 * x

(This means that 56 is less than or equal to 7 times x.)

We create this inequality because of how Joe will spend AT LEAST $56 dollars on candy. The amount of candy is not defined in the question.

Let's solve.

56 ≤ 7 * x

Divide by 7.

8 ≤ x

Joe will buy at least 8 pounds of candy,

Note the word at least. This states that he may buy more, however 8 is the minimal amount he will obtain.
