An elevator started on the first floor, went up 18 floors, then came down 11 floors and went back up 16. 1 + 18 - 11 + 16
1 - 18 - 11 + 16
1 + 18 + 11 - 16
1 - 18 + 11 - 16

1+18-11+16

Step-by-step explanation:

if the elevator went up it will be plus but if the elevator came down it will be minus and then you will get 1+18 because it went up and then it go down 11 floor and it will be 1+18-11 and then it went up again 16 floor so the last answer will be 1+18-11+16

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

this doesn't make sense lol
