Answer:
The telephone expense for first shop is $2284 and for second shop is $701.
Step-by-step explanation:
Let the telephone expense for first shop be x.
Also Let the telephone expense for second shop be y.
Given:
The total telephone expensive for both shops was $2985.
Hence,
[tex]x+y = 2985 \ \ \ \ equation \ 1[/tex]
Also given:
the telephone bill for the first shop was $520 less than four times the telephone bill for the Second shop.
Hence the equation can be framed as;
[tex]x=4y-520[/tex]
Substituting the value x in equation 1 we get;
[tex]x+y=2985\\4y-520+y=2985\\5y= 2985+520\\5y =3505\\y= \frac{3505}{5} = 701[/tex]
Substituting the value of y in equation 1 we get;
[tex]x+y=2985\\x+701=2985\\x= 2985-701\\x=2284[/tex]
Hence The telephone expense for first shop is $2284 and for second shop is $701.
