Penny is planning a baby shower for her daughter-in-law. The restaurant charges $950 for up to 25 guests, plus $31.95 for each additional guest. How many guests can attend if Penny wants the total cost to be no more than $1,500?

42

Step-by-step explanation: I subtracted 950 from 1500 and that left me with 550 that i divided by 31.95 which left me with 17... but we keep it at 17 because we can't have half of a guest. Then you would add 17 to the 25 other guests you are paying for the answer of 42

42

Step-by-step explanation:

1500-950=550

550÷32=17

17+25=42 guests

3x + 100 < 2x - 250

Step-by-step explanation:

The problem said that Keisha's guess was "250 less than twice the number".

It was written as 250-2x, which is actually twice the number less than 250, because we are subtracting 2x. We just need to write it like this:

2x-250

So the inequality should be:

3x + 100 < 2x - 250
