67, 79, 81, 83, 83, 85, 87, 88, 89 then find the bumber in middle so answer is 83
I think it is 45.00 because you multiply -4.50 x 5= -22.5. The reason you multiply x4.59 times 5 is because he takes away 4.50 every day for 5 days. And then you do 67.50-22.5=45.00.
It is a.1
(1+5) - 2(4(1)-1) = 0
(6) - 2(3) = 0
6 - 6 = 0
0=0
