Answer:
The total change is £21.02 from the original amount of £78.98. Therefore, the percentage change is directly related to the original amount.
so the answer in a percentage is 15.22%.
Step-by-step explanation:
First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:
-15.5t + 3.1t = -13.44 + 10.56 - 13.24
Now combine the numbers on both sides of the equation and solve for t:
-12.4t = -16. 12
t = 1.3
