A restaurant customer left $1.35 as a tip. The tax was 4% and the tip was 15% of the after tax cost. Which information is not needed to compute the bill after tax and tip? What
was the total bill?
Which information is not needed to solve this problem?

5x+2x=49

7x=49

x=7. 35 apples

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

first one because it can't have a fraction in it
