Solutions
We know that a ticket costs £14.50 and it is increased by <span>7% in price. To solve the problem lets use variables.
Let the Variable Y</span><span> = 7% of 14.5
Equation: Y = P% </span>×<span> (X)
Solve for our equation Y
Y = P% </span>×<span> (X)
Y = 7% </span>×<span> 14.5
Now lets convert the percent to a decimal:
Percent = Out of 100
Percent = 7% / 100 = 0.07
Y = 0.07 </span>×<span> 14.5
Y = 1.015
</span><span>

13+3k=11
-Move constant to the right-hand side and change its sign
3k=11-13
Calculate the difference
3k=-2
Divide both sides by 3
K= -2/3
