D

The coach splits a team of 27 students into 3 groups to practice skills. How many students are in each group?

Answer 1

C) $27 for 3 pizzas $35 for 4 pizzas

at first it seem to be 27/3 = $9 per pizza, but then 35/4 = $8.75 per pizza

There is a likely delivery charge, independent of how many pizzas are delivered

27 = 3P+D

35 =4P+D

subtract 1st from 2nd

P = $8 per pizza

27=3(8)+D

D= 27-24 = $3 delivery charge

3x=27, x=27/3=9 works for the other 3 options

A) 27/3 = 9 pages read by Noah

B) 27/3 = 9 friends

D) 27/3 = 9 students per group
