Answer:
[tex]20x+35y=1070[/tex]
[tex]x+y=37[/tex]
Step-by-step explanation:
Each cut for short hair costs $20, and each cut for long hair costs $35.
Let x represent the number of haircuts for short hair.
Let y represent the number of haircuts for long hair.
Part 1:
[tex]20x+35y=1070[/tex] .....(1)
Part 2:
The salon gave a total of 37 haircuts for short and long hair the first day.
[tex]x+y=37[/tex]
Further if you want to solve it:
Substituting [tex]x=37-y[/tex] in equation (1)
[tex]20(37-y)+35y=1070[/tex]
[tex]740-20y+35y=1070[/tex]
[tex]15y=330[/tex]
y = 22
And x = 37-y
[tex]x=37-22=15[/tex]
x = 15
Hence, there were 15 haircuts for short hair and 22 haircuts for long hair.
