Kindergartens 29031

We bought 50 kindergartens of two types for the kindergarten - milk for 16 CZK per piece and hazelnuts for 11 CZK per piece. We paid a total of CZK 700. How many chocolates were there?

Correct answer:

m =  30
o =  20

Step-by-step explanation:


m+o=50
16m+11o = 700

m+o=50
16·m+11·o = 700

m+o = 50
16m+11o = 700

Pivot: Row 1 ↔ Row 2
16m+11o = 700
m+o = 50

Row 2 - 1/16 · Row 1 → Row 2
16m+11o = 700
0.31o = 6.25


o = 6.25/0.3125 = 20
m = 700-11o/16 = 700-11 · 20/16 = 30

m = 30
o = 20
