November 7918

Zuzana receives pocket money from her parents. In October and November, she managed to save 32 euros. The ratio of cash held in October and November is 6:2. How much did she save in October and November?

Correct answer:

n =  8
o =  24

Step-by-step explanation:

o+n=32
o=6/2·n

n+o = 32
6n-2o = 0

Pivot: Row 1 ↔ Row 2
6n-2o = 0
n+o = 32

Row 2 - 1/6 · Row 1 → Row 2
6n-2o = 0
1.33o = 32


o = 32/1.33333333 = 24
n = 0+2o/6 = 0+2 · 24/6 = 8

n = 8
o = 24
