<human>:  Morgan's dad said that she had $90 budgeted for her birthday party. She wants to make sure she and her friends all get to play one round of mini-golf, have $5 in arcade tokens, and get to ride the go-karts twice. A round of mini-golf is $5. The Go-karts cost $10 a ride. How many friends can she invite?
<bot>: How many go-karts can she ride? ** The go karts will cost $20 per person because 10 x 2 = <<10*2=20>>20
How much does each person cost? ** Each person costs $30 because 5 + 5 + 20 = <<5+5+20=30>>30
How many people can she invite? ** Three total people can attend because 90 / 30 = <<90/30=3>>3
How many friends can she invite? ** She can invite 2 friends because 3 - 1 =<<3-1=2>>2
