Tom is 40 inches tall. The sign next to the Superman Roller Coaster says: “You must be 48 inches to ride!”. By what percent does Tom have to grow to be able to ride the roller coaster?

inches to grow=48-40=8

percentage of inches to grow to ride the roller coaster= 8/48×100

= 16.66%

WHO CARES ABOUT WHAT THE SUPERMAN ROLLAR COASTER SIGN SAYS JUST RIDE IT!! (jk :))

REAL ANSWER: 20%

Step-by-step explanation:

20% of 40 is 8. 40+8=48. Therfore, Tommy here has to grow 20%.

Hope this helped! If it did, please give me brainliest! It would help a lot! Thanks! :D
