Answer:
$140
Step-by-step explanation:
You can add up the prices to find the total. Most of us find it easier to multiply the price by the number of items.
cost of 2 shirts = (2)($25.00) = $50
cost of 4 pants = (4)(22.50) = $90
The total was $50 +90 = $140.
Elimination
2x+2y=10
2x-3y=5
multiply first equatn by -1
-2x-2y=-10
add to second equation
2x-3y=5
<u>-2x-2y=-10 +
</u>0x-5y=-5
-5y=-5
divide both sides by 5
-y=-1
muitply b-1
y=1
subsitue
2x+2y=10
2x+2(1)=10
2x+2=10
subtract 2
2x=8
divide 2
x=4
x=4
y=1
solution in (x,y) form is
(4,1)
