It increased by 7.5% if you subtract the starting value from the new one and then put that answer over the starting value.
keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

so we're really looking for the equation of a line with a slope of -2 and that passes through (1 , -1)

Answer:
Total number of choices with a straw: 12
Total number of choices without a straw: 12

- served in a small or large glass (2 options)
This made a total of 3*2*2: 12 different choices
if the drink can be served with or without a straw, he choices are doubled, making a total of 2*12 = 24
..........solve it like an equation
