Answer:
$6.70
Step-by-step explanation:
Adrian purchases a book for 4.86 and a poster for 3.44
The total amount he owes would be 4.86 + 3.44 = $8.30
If she gives the cashier 15 dollars she should receive 15 - 8.30 = $6.70 back.
C because first you do ( 4+2 ) = 6 and 10 - 6 = 4
x<6 is the answer sorry if its wrong
let's say "x" is the whole lot and thus the 100%.
we know 12 is 60%, how much is "x" or 100%?
