Answer 1

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

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.
