Ms. Sung budgets a maximum of $320 per month for groceries. She grocery shops 4 times a month. Which inequality can be used to find the possible values of x, the amount she can spend at the grocery store during each shopping trip?

Less than or equal to $80

Step-by-step explanation:

If she get $320 a month and shops 4 times a month, you have to find the unit rate. This is so that you know the maximum amount of money she can spend.

320:4=80

She can't go above $80, but she can spend any amount under $80. Than means the amount she can spend is less than or equal to $80.
