Sue bought ten items at an average price of $3.60. The cost of eight of the items totaled $30. If the other two items were the same price, what was the price she paid for each ?

1) $15, 2) $7.50, 3) $6, 4) $3, 5) $1.50

I guess the answer is $7.50.

ok soo if the 10 items avg $3.60 each then your total for the ten items was $36. if we know that the cost of 8 items is $30 then there is 6 dollars left. nd if we no that the remaining 2 are the same price then each should be $3
