$7.50

Step-by-step explanation:

2 hambugers cost $2.50*2 = $5.00

1 Fries = $1.50

1Soda = $1.00

Total cost = $5.00 + $1.50 + $1.00 = $7.50

Cost of one Hamburger = $2.50

Cost of a packet of Fries = $1.50

Cost of one Soda = $1.00

Total cost = The sum of his meal

Total cost = $ [ 2(2.50) + 1.50 + 1.00 ]

Total cost = $ ( 5.00 + 1.50 + 1.00 )

Total cost = $ 7.50

The total cost of his meal was $7.50 .

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
