At dinner a meal cost 22 and the sales tax of 1.87 was added to the bill how much would the sales tax be on a 66 meal

$5.61

Step-by-step 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
