Answer: p= 25n/7 358
n will be the total number of students on the field trip
g could represent the number of groups
p will represent the number of pencils
For this situation with 100 students, John will need 358 pencils. for 14 2/7 groups.
To be safe, since he has a partial group, he should round up to 15 groups and get 375 pencils. Especially if the pencils only come in boxes of 25, and he can't buy a partial box.
Step-by-step explanation:
25g = p
g =n/7
Combine these to get the ratio
g becomes unnecessary
p= 25n/7
the exact calculation for g was 100/7 = 14.28571
The exact calculation for p = 100/7 × 25 = 357.142857
But you can't buy partial pencils!
