Mary works selling cards over the telephone. She sells two types of cards: birthday cards and holiday cards. Mary makes $2.00 for each box of birthday cards she sells, and $2.50 for each box of holiday cards she sells. She can work no more than 10 hours per week. It takes
her an average of 15 minutes to sell one box of birthday cards, and an average of 20 minutes to sell one box of holiday cards.
If she can sell no more than 35 boxes of cards in total, how many boxes of each type should she sell to make the most money? (Hint:
remember that an hour contains 60 minutes!)

-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

the correct option is b
