Answer:
Cost of one glove pair is $ 8.50 and the cost of one hat is $6.50
Step-by-step explanation:
Let g represents the cost of one gloves pair
h represents the cost of one hat
Then
Cody brought two pairs of gloves and four hats for $43.00
This can be written as
2g + 4h = 43-------------------(1)
Tori bought two pairs of gloves and two hats for 30.00
This can be written as
2g + 2h = 30------------------(2)
Subtracting (2) from (1)
2g + 4h = 43
2g + 2h = 30
(-)
--------------------------
0g + 2h = 13
------------------------------------
2h =13
h = 13 / 2
h = 6.5---------------------(3)
Substituting (3) in (2)
2g + 2(6.5) = 30
2g + 13 = 30
2g = 17
g = 17 / 2
g = 8.5
So one hat is $6.50 and one pair of gloves is $8.50.
First let
, so that
to write the integral as
Now recall that
, so substituting
should do the trick. The integral then becomes
