The answer would be 747.50! Because if you were wanting to decrease the price then you would multiply $299 by 40% So since you are wanting to add to the price then you would divide...Hope that makes since :)
Number line graph with closed circle on 30 and shading to the right because you already have 30 dollars and they need at least 120 but if they get more then 120 they can still hold the science fair.
