It is 45% of 247 move the the decimal on the 45% two places to the right, then you should get .45. Of means multiply so .45*247 should get you the answer of 111.15 that's how you find the percent of this number. If you round the answer you would get 111 so about 111cars had a sunroof
Cost of Taxi A = $ 0.20*X + $4 With "X" equal to "miles traveled". For taxi B we have: Cost of Taxi B = $ 0.40*X + $2 Then, when Cost of Taxi B > Cost of Taxi A,
We Have: $ 0.40*X + $2 > $ 0.20*X + $4
That is the inequality that you need! Good luck! M.
