A $129.50 camera that is on sale for 40% find the sale price

It is $51.80.

Step-by-step explanation:

In order to find the new price, we must find 40% of 129.5. This is simple. We know that 40% is equal to .4. Therefore, you can find the answer by simply multiplying .4 by 129.5.

129.5(.4) = 51.8

Therefore, 40% of 129.5 is 51.8. In order to convert this to money, we can put a 0 at the end and add a $ sign to the front.

Your new answer is $51.80.

Hope this helps!

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
