Answer 1

Answer: $8a+a-3=6a-2a-3\n\n9a-3=4a-3\ \ \ \ /+3\n\n9a-3+3=4a-3+3\n\n9a=4a\ \ \ \ /-4a\n\n9a-4a=4a-4a\n\n5a=0\ \ \ \ /:5\n\n5a:5=0:5\n\na=0$

Answer 2

Answer: Ok so => 8a + a -3 = 6a -2a -3
9a - 3 = 4a -3
-3 on both sides is gone so 9a = 4a
9a - 4a =0 => 5a = 0 so a=0

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The cost of meal and a beverage = $14

The tip = 20%

The sales tax = 6%

Now,

Since, The cost of meal and a beverage = $14

Hence, The cost for tip = 20% of 14

= 20/100 x 14

= $2.8

And, The cost for sales tax = 6% of 14

= 6/100 x 14

= $0.84

Thus, Total cost of the meal = $14 + $2.8 + $0.84

= $17.64

Therefore, Total cost of the meal will be $17.64.
