42 * 0.18 = $7.56
She gave the barbar $7.56 in tip
Answer:
I think its -20/33- Im not that confident but i worked it out :)
Okay so the two equations are (b-book d-dvd)
d-4=b
and 3d+b=28
so to solve this if we know that a dvd costs £4 more than a book and we have 3 of them then if we take 3 lots of 4 away from the 28 then we will have an amount equal to 4 books
so 28-12=14
14/4= £3.50
if 1 book is £3.50 then a dvd is £7.50 as it is £4 more
-9.1 < d - 6.3
add 6.3 to both sides
-2.8 < d or d > -2.8
