Answer:
£44
Step-by-step explanation:
In order to use Brett's simple percentage discount logical answer, we can form an equation for it given by;
[tex] \sf \implies 80 - (80 \times 0.45)[/tex]
Noted by the equation, We subtract the value of 45% of £80 from the initial £80
Solution:
[tex] \sf \implies 80 - (80 \times 0.45)[/tex]
[tex] \sf \implies 80 - (36)[/tex]
[tex] \sf \implies \pounds 44[/tex]
Therefore, the sale price after the percentage discount according to Brett's equation would be £44
