The cakes are orange or lemon cakes.
Each day flora takes a sample of 25 cakes to check.

Answer:
A) 210
B) 0.18
Step-by-step explanation:
A) On Monday, 7/25 of the 750 are orange cakes. 7/25 x 750 = 210
B) If the proportion of orange cakes is 5/25 where 5 is correct to the nearest whole number, then the 4.5 would be the lowest number that would still be rounded up to 5. 4.5/25 = 0.18
