what is your own attempt?

anonymous · Answer

I have no freakin Idea wut 2 do..

amistre64 · Answer

well, if something is going to be reduced from its original price ... id suggest starting with the original price

anonymous · Answer

I guess so

amistre64 · Answer

if we take the original y amount, but only want .22 less of it, then we keep .78 of it

.78y  is going to be the price that we take to the register

amistre64 · Answer

now we want to add to it the sales tax, which is just an extra 6%

amistre64 · Answer

Im so lost..

anonymous · Answer

So what IS the final cost of cards?

amistre64 · Answer

well, if 75% of y is equal to: .75y

the 6% of .75y is equal to:  .06(.75y)

and this is added to what the sales price is soo

.75y + .06(.75y)  is the final price we pay
