A pair of pant and a t-shirt cost $30. If the pant cost $6.28 more than the shirt, how much did the pant cost?

Lets let "p" represent pants and "s" represent shirts. If the total purchase was $34 then we can assume that

p + s = $34.

If the pants cost $5.28 more than the shirt, then we can say that  p = s + $5.28. Lets substitute this into the original equation ==> (s + $5.28) + s = $34

Now, lets combine like terms ==> 2s + $5.28 = $34

Solve for s ==> 2s + $5.28 = $34 ==> 2s = $28.72 ==> s = $14.36

Now lets plug in the value of s into the original equation ==> p + (14.36) = $34

Solve for p ==> p + $14.36 = $34 ==> p = $19.64

Therefore the pants cost $19.64 and the shirt costs $14.36

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
