You buy a book for 10.99 dollars and pay $0.91 in sales tax how much change should you receive from a $20 bill explain your work

$8.10

Step-by-step explanation:

The first step is to calculate how much you owe.

10.99 + .91 = 11.90

Change = Cash paid - how much you owe

               = 20.00 - 11.90

                =8.10

The change is $8.10

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
