Question 652169: Hi there! Stupid stuck! (Again!)
Joe buys five shirts and three shorts for $51.
Bill buys three shirts and seven shorts for $80.
How much does each shirt and each pair of shorts cost.
So, if x is cost of each shirt
And if y is the cost of each pair of shorts, wouldn't the restated problem be:
8x + 10y = $131? Where do I go from here. I am stuck, again. Found 2 solutions by nerdybill, MathLover1:Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! Joe buys five shirts and three shorts for $51.
Bill buys three shirts and seven shorts for $80.
How much does each shirt and each pair of shorts cost.
So, if x is cost of each shirt
And if y is the cost of each pair of shorts
.
gives you the "system of equations":
5x + 3y = 51
3x + 7y = 80
solve by the "addition method".
multiply top eq by 3 and bottom eq by -5 then combine both:
15x + 9y = 153
-15x -35y =-400
----------------
-26y = -247
y = $9.50 (shorts)
.
shirts:
5x + 3y = 51
5x + 3(9.50) = 51
5x + 28.50 = 51
5x = 22.50
x = $4.50
You can put this solution on YOUR website! given:
Joe buys shirts and shorts for $.
Bill buys shirts and shorts for $.
if is cost of each shirt and if is the cost of each pair of shorts, than we have:
....1....what Joe buys
....2....what Bill buys
____________________________________.....solve the system
....1...solve for ..........plug it in 2 and solve for ....2
....each term multiply by ..........cost of each each pair of shorts
now find ......cost of each shirt
