Aperson owns two shops. this year the telephone bill for the first shop was $560 less than three timesthree times the telephone bill for the second shop. the total telephone expense for both shops was $2752. what was the cost of each shop's telephone service for the year?

The telephone bill for the first shop is $1924 and for the second shop is $828

Step-by-step explanation:

Let's call A the cost of the telephone service of the first shop, and B the cost of the telephone service of the second shop.

From the sentence, the telephone bill for the first shop was $560 less than three times the telephone bill for the second shop, we can formulate the equation 1, as:

A = 3*B - 560

Additionally from the sentence, the total telephone expense for both shops was $2752, we can formulate the equation 2 as:

A + B = 2752

For found the values of A and B, we need to take A from equation 1 and replace its value on equation 2, and solve for B. This is:

A + B = 2752

(3*B - 560) + B = 2752

3*B - 560 + B = 2752

4*B = 2752 + 560

4*B = 3312

B = 3312/4

B = 828

Replacing the value of B on equation 1, we get:

A = 3*828 - 560

A = 2484 - 560

A = 1924

So, the value of A is 1924 and the value of B is 828, That means that the telephone bill for the first shop is $1924 and the telephone bill for the second shop is $828

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
