Answer:

Pencil: $1.50

Notebook: $3

Step-by-step explanation:

n = cost of notebook

p = cost of pencil

n + p = 4.5

n = 2p

substitute n into the first equation

2p + p = 4.5

3p = 4.5

p = 1.5

n = 2p

n = 2(1.5)

n = 3

50=2(pi)r

r=50/2(pi)

r=7.96


Use this to solve for area

A=(pi)r^2

A=(pi)(7.96)^2

A=199cm
