Lorenzo buys 3 shirts at s dollars apiece and 2 pairs of pants at p dollars a pair. what does the expression 3s+2p represents?

Let

s--------> the cost in dollars of a piece of shirt

p-------->  the cost in dollars of a pair of pant

T-------->  total cost of Lorenzo's buy in dollars

we know that

therefore

the answer is

the expression represents the total cost of Lorenzo's buy in dollars (the total cost of the 3 shirts and the 2 pairs of pants)

1.4

2.3

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
