Joe spends $8 for lunch and $6.50 for dry cleaning. he also buys 2 shirts that cost the same amount. joe spends a total of $52. what is the cost of each shirt?

The correct answer is $18,75.

Step-by-step explanation:

We must start by analyzing the information we have.

We know that Joe spends $ 8 for lunch and $ 6.50 for dry cleaning. And that buys 2 shirts of which we do not know their value but we know that they cost the same each.

We have as data that Joe has spent a total of $ 52, so we must put together the following equation:

8 + 6.50 + 2.x = 52

Now we just have to solve it:

14.50 + 2x = 52

2x = 52-14.50

2x = 37.50

x = 37.50: 2

x = 18.75

In this way we can say that each shirt costs $ 18.75 each.

b is the final answer! : )

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
