Answer: $107

Step-by-step explanation:

Tip = 20 % of $90

= 20/100 × $90

=$18

Sales tax at 10% = 10/100 × $90

= $9

Total cost= $90 + $18 + $9

= $107

Answer:

117

Step-by-step explanation:

90 times 1.1 (the 1 is for the total amount which is ninety and the .1 is for 10% because you have to move the decimal over 2) is 99

90 times .2 equals 18

you then add 99 to 18 and the answer is 117
