# Seamstress

Seamstress bought two kinds of textile together 25 meters. One at 50 SKK and the second 70 SKK per meter. How many meter bought from this two textiles when paid totally 1540 SKK?

Result

x =  10.5 m
y =  14.5 m

#### Solution:

50 x + 70 y = 1540
x+y = 25

50x+70y = 1540
x+y = 25

x = 212 = 10.5
y = 292 = 14.5
