After the increase in the dimensions of the sign, the effect on the area of the sign is that the new area is 8 times larger than the initial area.
The sign has the shape of a rectangle. A rectangle has four sides. The opposite sides are equal in length.
The area of a rectangle = length x width.
Jimmy is making the sign bigger by increasing the size of the length and width. Let's imagine that the width is 8cm and the length is 10cm.
The initial area of the sign = 10 x 8 = 80 cm
After the increase in the dimensions, the length is are 40cm and 16cm for the width.
New area = 40 x 16 = 640
Number of times the new area is greater than the initial area = 640 / 80 = 8 times larger

Answer:
a. Take a grid that shows represents the amount of money Frank has,
Say F,
( shown below ),
b. Since, Marissa has twice as much money as Frank,
So, the amount Marissa has = 2F
If M represents the amount Marissa has,
M = 2F
c. Now, Christina has $20 more than Marissa,
Add 20 to the grid M
d. The below diagram provides enough information to determine the value of the variable m
e. The amount Christina has = M + 20 = 2F + 20
According to the question,
2F + 20 = 100
2F = 80
F = 40
Hence, the amount frank has = $ 40,
Amount Marissa has = 2(40) = $ 80,
