Hannah serves tables at a restaurant. the first table she served on a monday paid her $78.20. the bill amount was $68.00, and the rest was hannah's tip. what percentage of the bill was hannah tipped?

Hannah tipped was 13% of the bill.

Step-by-step explanation:

$78. 2 - $68 = $10. 2

$10. 2/$78. 2 × 100 = 13.04 = 13%

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
