Doss [256]

Answer:

She can buy no more than 22 decorations

Step-by-step explanation:

The costs for the party are food and decorations

Cost = food + decorations * costs per decoration

We can spend no more than 300

Food is 75

Decorations are 10 each

Let d= the number of decorations

300 >= 75 + 10 * d

Subtract 75 from each side

300-75 >= 75-75 + 10 * d

225 >= 10d

Divide each side by 10

225/10 >=10d/10

22.5 >=d

She can buy no more than 22 decorations
