In calculating interest by the previous balance method, purchases and payments during the month are not counted in calculation of interest.
Well its $16
for 4 tickets so u multiply everything by four and get $64 for 16 tickets
2x+20=58 then your would subtract 20 from 58 which would turn into 38 and your would divide 38/2 it would be 19 so the answer is x=19 if I’m not mistaken this is correct hope this helps
The answer should be -3, I can explain it if you want.
