Robert is traveling to Mexico for a family vacation. He is bringing 625 U. S. dollars with him. Robert needs to exchange his money for Mexico's currency, pesos. If the exchange rate is 13.25 pesos for every dollar, how many pesos should Robert get in exchange?
A
47.17 pesos

B
611.75 pesos

C
638.25 pesos

D
8281.25 pesos

Robert should get D. 8281.25 pesos in exchange.

Explanation:

it should be a and d. lmk if i'm wrong xd

-3

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
