Part 2 Bonnie is obsessed with making perfect milkshakes. To her, the perfect milkshake must contain exactly 3 scoops of ice cream to 1 cup of milk. She refuses to make any milkshake with more or less than that ratio of ice cream to milk, and will simply throw out any extra of an ingredient. She wants to make as many milkshakes as possible. She shops at Safeway where ice cream is sold at a price of $1.50 per scoop and milk sells for $0.50 per cup. She has $20 in income to spend. 6.
