Answer 1

The possible numbers of pounds she will buy is less than 6.

Explanation:

Given : Donna buys candy that costs $5 per pound. She will spend less than $30 on candy.

To find : What are the possible numbers of pounds she will buy?

Solution :

Let x be the number of pounds.

Donna buys candy that costs $5 per pound.

i.e. cost of x candy is $5x.

She will spend less than $30 on candy.

i.e.
`5x<30`

Solve the inequality,

`x<(30)/(5)`

`x<6`

The possible numbers of pounds she will buy is less than 6.

Answer 2

x = number of pounds

5x<30

x<30/5

so she can buy X<6 pounds
