Gwen has £0.75 money left over, as per linear equation.
What is a linear equation?
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation."
Given, Gwen has a £5 note and a £2 coin.
Therefore, she has a total of £(5 + 2) = £7
A liter of cola costs £1.25.
Therefore, (7 ÷ 1.25) = 5.6
Therefore, Gwen can buy a total of 5 liters of cola.
Now, Gwen has left money of £[7 - (5 × 1.25)] = £0.75
