Peter is eating chips. Each chip is 10 calories. A bag has 24 chips and costs $2. If he wants to eat 480 calories, how much does he have to spend on chips?
Each bag has 240 calories because 24 x 10 = <<24*10=240>>240
He needs two bags because 480 / 240 = <<480/240=2>>2
It will cost $4 because 2 x 2 = <<2*2=4>>4
