12. Currently, there are 350 students in the seventh grade at Winchester
sweet [91]

Answer:

Winchester Heights Middle School plan to have 385 students in the  upcoming school year.

Step-by-step explanation:

Total number of students in the seventh grade at Winchester  Heights Middle School = 350

For the upcoming school year, they are planning to  increase the number of seventh graders by 10%.

Rate of increase = r = 10% = 0.1

Formula :N(t)=N_0(1+r)^t

Where N_0= initial population = 350

r = rate of increase =0.1

N(t)=Population after t years

t = time in years

So, Population after 1 year = 350(1+0.1)^1 =385

Hence  Winchester Heights Middle School plan to have 385 students in the  upcoming school year.
