Taryn is hosting a party at a restaurant. The restaurant is charging her $160 to rent the space and $20 per guest. If Taryn wants to spend less than $660, which inequality could be used to solve for x, the number of guests Taryn can invite?

EXPLANATION:
Let the no. of guests be x.

x = (660-160)/20
=> x = 500/20
=> x = 25

ANSWER: He can invite 25 guests.

ALTERNATIVE METHOD:
Money needed to rent the space= $160
His budget= $660
So, money left= $(660-160) = $500

Money needed per guest= $20
Guests he can invite with his budget= 500/20 = 25

So, He can invite 25 guests.

Hope it helps u!

The real answer is 6 gallons
