Answer 1

Step-by-step explanation:

The derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus

Answer 2

Answer:

8.75 per cake

Step-by-step explanation:

250 cakes at rate of 7

so C.P.=250*7=1750

now gain need is 20%

so S.P.= 1750*1.2=2100

now 10 cakes are spoiled so remaining are 250-10=240

so required price=2100/240=8.75 per cake
