One day you went to the three dollar store. of course all items you chose were $3. this store is a city with no sales tax on food, but an 5% tax on non food items. you paid the bill of $34.05. how many of each type of item did you buy?

I buy 4 food items and 7 non-food items from the store.

Step-by-step explanation:

The food items in the store are sold at $3 each and the non-food items are sold at $3 plus 5% tax.

So, the cost of each non-food items will be dollars.

If we consider that I buy 1 food item, then I buy $(34.05 - 3) = $31.05 of non-food items which is not a multiple of $3.15.

If I buy 2 food items, then I buy $(31.05 - 3) = $28.05 of non-food items which is again not a multiple of $3.15.

If we consider that I buy 3 food items, then I buy $(28.05 - 3) = $25.05 of non-food items which is again not a multiple of $3.15.

If I buy 4 food items, then I but $(25.05 - 3) = $22.05 of non-food items which is finally a multiple of $3.15 as (3.15 × 7) = 22.05.

Therefore, I buy 4 food items and 7 non-food items from the store. (Answer)

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
