Answer:
$5.61
Explanation:
The information that we have is that the sales tax on the $22 meal was $1.87.
Cost sales tax
$22 ⇒ $1.87
And we need to know the sales tax on a meal of $66.
Since $66 is 3 times $22
3($22)=$66
the sales tax must also be 3 times bigger:
3($1.87)= $5.61
The sales tax on a $66 meal is $5.61
Cost sales tax
$22 ⇒ $1.87
$66 ⇒ $5.61
