At dinner, the meal cost $22 and a sales tax of $1.87 was added to the bill. "What would be the total amount if the meal cost $80?" *

$86.8

Step-by-step explanation:

Step one:

Given data

At dinner, the meal cost $22 and a sales tax of $1.87

let us find what percent $1.87 to the cost of the meal

= 1.87/22*100

=0.085*100

=8.5%

Hence the sale tax is 8.5%

Step two:

if the cost is now $80

the sale tax will cost

=8.5/100*80

=0.085*80

=$6.8

The total will be

=80+6.8

=$86.8
