There is 1 orange for every 3 apples. It can be expressed at 1:3 oranges to apples.
In order to find this, first count the number of each. We have 2 oranges and 6 apples. Since both have factors of 2, divide both numbers by two. This will give you the answer above.
C^2 + 11c = 12
c^2 + 2[11/2] c = 12
[c + 11/2] ^2 - [11/2]^2 = 12
[c +11/2]^2 = 12 +[11/2]^2
[c +11/2]^2 = 12 + 121/4
[c +11/2]^2 =[48+121]/4
[c +11/2]^2 = 169/4 ----> This is the resulting equation
Solving it you get:
c + 11/2 = +/- √(169/4)
c + 11/2 = +/- 13/2
c = 13/2 - 11/2 =2/2 = 1 and
c = -13/2 - 11/2 = - 24/2 = -12

Let the answer be x percent:
So we say: the tax is x% of the price,
this means: $3.56 is x% of $89
"something %" means 1/100 times something,
thus, we write and solve the following equation:
Answer: the tax is 4%
