X= sales tax %
Step 1:
$240 * sales tax %= $12
240 * x= 12
240x=12
Divide both sides by 240
x= 0.05 (decimal of the %)
Convert to %:
Multiply decimal by 100 (or move decimal to the right two decimal places
=0.05 x 100
=5 %
The sales tax is 5%.
Hope this helps! :)
Okay so we have
$1.60 x .10 = .16
1.60 - .16 = $1.44
so
1.44 x 4 = $5.76
1.44 / 2 = .72
$5.76 + .72 = $6.48
so your answer is $6.48 [B]
