B.)28
because the width 6 times 2 is 12
the length 8 times 2 is 16
16 plus 12 = 28
Y=-2x+b
1=-2*(1)+b
1=-2+b
B=1+2=3
Y=-2x+3
2x+y-3=0
A is the answer to ur question
Rewrite the sales tax as a decimal by moving the decimal point 2 places to the left.
8% = 0.08
Ow multiply that by the price:
42 x 0.08 = 3.36
The sales tax is $3.36
