Answer:

Step-by-step explanation:

a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %

b) Let the number of pies sold = x

45% of x = 90

[tex]\dfrac{45}{100}*x=90\\\\\\x=90*\dfrac{100}{45}\\\\\\x=2*100\\[/tex]

Number of pies = 200

c) Number of cheese filling = 30% of 200    

                                             [tex]=\dfrac{30}{100}*200\\\\= 30*2\\\\\\= 60[/tex]

Number of beef pies = 25% of 200

                                   [tex]=\dfrac{25}{100}*200\\\\\\=25*2\\\\= 50[/tex]

Difference = 60 - 50 = 10

There are 10 more cheese pies than beef pies.
