A community action committee is planning a block party. The party will be successful only if at least 70 adults and children att
Sergeeva-Olga [200]

Answer:

A. a + c ≥ 70; 15a + 4c ≤ 1000

Step-by-step explanation:

<u>Given data:</u>

A community action committee is planning a block party

The party will be successful if at least 70 adults (a) and children (c) attend

Their budget for the party is $1,000

The cost for each adult will be $15

And the cost for each child will be $4

<u>Solution:</u>

<u />

At least 70 adults and children attend.

So the inequality here is a + c ≥ 70

The budget for the party is $1,000.

So the cost for all adults plus the cost for all children cannot exceed $1,000

And hence the inequality here is; 15a + 4c ≤ 1,000

How can I remember the special right triangle formulas?
lara31 [8.8K]
Maybe you can study it or figure out a trick. I usually study with my sibling, but if you don't have any, friends or other family. I am sure they won't mind. Also, maybe making flashcards, those work well. 
Also, you can print out worksheets and make your brain remember. PRACTICE!
