1. Edison School PTA held a craft bazaar during the school year. The PTA sold money. Altogether, they sold 688 items that totaled $9,116.
a.
If the PTA sold each item for the same price, calculate the price of eac
$9,116 + 688= 1

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

The answer is
