Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.42.
2 answers:
Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as: c(p) = 0.42p Where: c(p) = total cost of sugar bought p = pounds of sugar c(p) is a function of p, because c(p) depends on p.
Answer: The function rule that gives the total cost is given by
Step-by-step explanation:
Let the number of pounds of sugar be 'p'.
Let the total cost would be C(p).
Cost of each pound = $0.42
So, the function rule would be
Hence, the function rule that gives the total cost is given by

Answer:
693
Step-by-step explanation:
7*9*11*3=693
Ok so we know that consecutive angles are supplementary and the diagonals bisect the angels so
2x-15+3x=90
5x=105
X=21
