suddenly the number of math problems mathletes had to solve increased by 60%! to keep on track the mathletes try to go faster but only increase their speed by 25% By what percent must the number of mathletes on the team increase so they can solve all the problems on time?

Answer :

Answer:

28%

Step-by-step explanation:

Lets say the fraction of speed and problem solved is 100/100

the number of problems solved increases by 60%

so now it is 160/100, also the speed increases by 25%

so now we do 160/125=1.28

finaly we do 1.28-1 = 28%

Therefore the answer is 28%.

hope this helps
