+82 Thanks to everybody who helped me with these series of problems I've posted. I really like this community and how helpful they can be, without this website I wouldn't have been able to complete this test with the 100% I'm sure I'm going to get on it. I really appreciate it.
Pretty simple. Seven more means you stick a (+7) on the end. Two times mean you multiply it by two. "The difference of yesterday's temperature high and 7" means (whatever yesterday's highest temp was) - 7. So the end expression is
2 x (temp - 7) +7
which equals
(2temp - 14) +7
which equals
2temp - 7
Or at least, that's what it ought to be.
