Kaitlan sold 60% of her hockey card collection at the fall market sale. If she sold 240 cards, how many cards were in her collection?

400

Step-by-step explanation:

Ok so if 60% of the total is 240 than create an expression:

60% of x=240

Now divide both sides by 3:

20% of x=80

Multiply both sides by 5 ( because 5 times 30 is 100):

100% of x=400

Thats the answer hope this helped! :)

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
