Mr. ochaeta is marking up all the prices of a basketball that costs 40$ is marked up to a new price of 45$. by what percent did mr. orcheata mark up the price?

a: 1.25%
b: 88.8%
c: 8%
d: 12.5%

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%

How many is in each case if there is 12 in each case it would be 40
