Answer:
Step-by-step explanation:
To increase 350 by 42% you multiply 350 by 1.42.
The reasoning for this is that you want to keep the original 350 because it is increasing from said number, so you need to multiply by at least one. Then to get the additional 42% you multiply it by its decimal equivalent .42. So together that is 1.42.
