The amount of butter used is an illustration of equivalent ratio
The amount of butter used last month is 300kg
Because the bakery used 25% more last month, the amount they used is then calculated using:
[tex]\mathbf{Amount =(1 + 25\%) \times Last\ month}[/tex]
Substitute 240kg for Last Month
[tex]\mathbf{Amount =(1 + 25\%) \times 240kg}[/tex]
Express percentage as decimal
[tex]\mathbf{Amount =(1 + 0.25) \times 240kg}[/tex]
Remove brackets
[tex]\mathbf{Amount =1.25 \times 240kg}[/tex]
[tex]\mathbf{Amount =300kg}[/tex]
Hence, the amount of butter used last month is 300kg
