a putt put offer a deal when you purchase 10 rounds of golf,you get 1 round for free,If you played a total of 35 rounds how many rounds did you purchase

Respuesta :

10+1=11
every 11
find how many 11's there are
35/11=3.18
so about 3 of the 11's

3*11=33
35-33=2

so out of every 11, yu purchase 10
so
10 times 3=30
then plus those 2
32 purchased
you purchased 14 roundss!!!
