A used-boat dealership buys a boat for $2800 and then sells it for $4000. What is the percent increase?

i will make the brainlist

Step-by-step explanation:

percent increase = increase divided by original number x 100

increase is the difference between the two numbers ...

new number - original number ... 4000 - 2800 = 1200

percent increase = (1200 / 2800) x 100

= 0.42857 (round to. 4286) x 100

= 42.86 % ... if you need it rounded to the nearest percent, it would be 43% increase
