Kindergarten 16593

The kindergarten purchased 40 chocolates of two types. Dairy is sold after 16 CZK per piece, and hazelnut after 11 CZK per piece. They paid a total of CZK 565. How many chocolates were there?

Correct answer:

m =  25
o =  15

Step-by-step explanation:


40= m+o
16m + 11o = 565

40= m+o
16·m + 11·o = 565

m+o = 40
16m+11o = 565

Pivot: Row 1 ↔ Row 2
16m+11o = 565
m+o = 40

Row 2 - 1/16 · Row 1 → Row 2
16m+11o = 565
0.31o = 4.69


o = 4.6875/0.3125 = 15
m = 565-11o/16 = 565-11 · 15/16 = 25

m = 25
o = 15
